  1. Nice upgrade. I had thought about swapping some 987 seats into my 986, but the deal fell through. When I was thinking about 987 seats, I was concerned that I would have trouble determining how to connect the heat, power and memory. It looks like you have conquered the power issue. Do you have heat and memory? I made several gradual upgrades to my unheated two-way power seats over the years. I went through several intermediate steps in my upgrade path and eventually ended up with a heated 12-way power seat on the driver's side and an 8-way heated seat for the passenger. I have attached a document I developed based on my experience. Upgrading Two-Way Power Seats.pdf
  2. I think you are right about the function of the 4 channel Haes amplifier. It would probably work well if you want to retain it to power the dash speakers (I hope the previous owner replaced those too) but I suggest you assess the pros and cons of an additional amp for the door and rear storage box speakers. I added a subwoofer and pair of rear-deck speakers to my 2005 Mercedes C230. I bought a "scratch and dent" 4-channel Kicker amplifier from Crutchfield for around $100 to power the speakers. I bridged two channels for the sub and the other two channels power the rear-deck speakers. I think that the amp I bought would fit in the space on the passenger side of the spar tire where the OEM 6-CD changer would be installed in a 986. I saw pictures on an installation that used the OEM CD-changer bracket to support the amp. The Boxster is not the best environment for music, but I found that installing speakers in the storage box makes a noticeable improvement in the sound quality when I drive with the top down.
  3. When I installed my rear speakers (in the storage box behind the seat) I replaced the 4-channel amp with a 6-channel amp from a 996 Cabriolet. Is it possible that the wiring diagrams you reference in your statement that, "Several wiring diagrams suggest that a second (rear) channel may be available from the amp to drive any additional rear speakers, or a set of full-range door speakers," are 996 wiring diagrams? Please note that you can power rear speakers from the CDR 220 head unit. This article explains how to do it: Rear speaker install Since I completed my rear speaker installation, I've done audio upgrade work on other family vehicles. If I were to do this project today, I would purchase an after market amp rather than use the HAES equipment. A good after market amp has controls that allow you to adjust gain and bypass settings to achieve better sound quality. I used the HAES 6-channel amp because it was easy to install and wiring it only required a minor adjustment to the amp harness connector.
  4. If you want to DIY the programming the instructions are in this thread: Cluster Upgrade - Rennlist - Porsche Discussion Forums RENNLIST.COM Boxster & Boxster S (986) Forum - Cluster Upgrade - Was considering a 996 cluster upgrade for my 1999 Boxster base. There is some confusion as to whether the cluster needs to be reprogrammed to work in the boxster. I know mileage correction is necessary but there's talk about adding Vin...
  5. This thread on Rennlist discusses transplanting a 996 cluster into a 986: https://rennlist.com/forums/boxster-and-boxster-s-986-forum/1144355-cluster-upgrade.html#post15876755 It includes instructions for transferring mileage and VIN information between clusters.
  6. Here's a link that I was planning to use as my starting point: Pelican Technical Article: Installing 997 Seats Into a 986 Boxster WWW.PELICANPARTS.COM In this article we'll show how to install 997 seats into a 986 Boxster Unfortunately, I was unable to purchase the seats (the seller was driving from Canada to Road Atlanta and I was planning to meet him in Roanoke. One of his companions was supposed to put the seats in his trailer, but forgot.) Therefore, I don't have any first-hand knowledge to share. I later found a set of seats (12-way driver, 8-way passenger) from a 996 Turbo that had been converted to a race car and installed them instead. I have attached the (rough) notes that I compiled before I changed plans and the 987 wiring diagram. I have some wiring and connectors from a 987 that I had planned to use in the project. Let me know if you think they will be useful. I recently adapted a set of Mercedes C63 AMG seats to work in the 2005 Mercedes C230 that I use as a daily driver. You can read about it here: Seat swap - 2009 C63 - MBWorld.org Forums MBWORLD.ORG C-Class (W203) - Seat swap - 2009 C63 - I will be meeting with a guy who is parting out a 2005 C230 some time this week. I need to replace the front wheel liners and I will also be looking to see if he has any trim that can upgrade some of my cosmetically challenged parts. The seller told me that... The seats in my Mercedes and Porsche work differently, but you may be able to glean something useful from my false starts and eventual (but delayed) completions of the project. I think you will be facing some of the same issues I encountered putting later generation seats into an earlier car. Because my C230 did not come with memory seats, I decided it would be too expensive and perhaps not technically feasible to make use of the memory function in the C63 seats. Mercedes uses a Canbus system to send data such as the signals that control seat memory. through out the car. If Porsche adopted a similar system, you may be in for quite a challenge. In addition to the seat motors, you will need to deal with the air-bag related seat occupancy sensor. If the 07 Caymans have the side impact air bags in the seats, you will need to ensure that you deal with them safely. If the seats are heated, that will be another challenge. Good luck with your project. Cayman seat info.pdf Cayman(987) 2006 Wiring Diagram - CU Seats.pdf
  7. The first thing I would check is any cluster-related fuse. A friend of mine blew the fuse to his radio when he jump-started his Boxster. It sounds like you could have experienced a similar problem.
  8. I'm not an expert on electronics, so please use my advice with caution. I did use Denis Vogel's instructions to install heated seats in my car, and based on that experience, I am offering these suggestions. Here's a link to a picture of the seat heater relay with the wiring: Seat Heater Relay with Wiring There are 7 wires: Red/White 2 brown Red/yellow Yellow/white Black/yellow Red/violet The red/white is power and the brown is ground. The other wires are the control wires from the switches. The red/white wire leaves the relay and goes to a connector that has the wire for routing current through the heating pad in the seat back. Another red/white wire comes out of the connector and goes to another connector to provide current for the heating pad in the seat bottom. A brown wire exits that connector and runs to the ground in the relay. I think what you need to do is connect the red wire (which I think is power) in your heating pads to the red/white wire from the relay and the black (ground) wire from your heating pads to the brown wire of the relay. You want to hook the heating elements for the seat back and seat bottom in series so that the current flows through one and then the other. The control wires will be connected as outlined in Denis Vogels' instructions.
  9. Hi, I'm embarking on a project to install heated 12-way memory seats from an 07 Cayman into my 986 Boxster. I've found some guidance on how to do it, but I am searching for better options. In order to make sure I'm doing thorough research, I need access to the wiring diagram for the 07 Cayman seats. Does anyone have the diagram or can tell me where to find it? Thanks, Kevin
  10. You should be able to find what you need in this: http://www.dennisvogel.com/heatedseats/
  11. Try Palo Alto Speedometer and North Hollywood Speedometer. I have seen several posts from folks who indicate that they have reset mileage on a replacement cluster. You could also reprogram a cluster yourself by copying files from your cluster to the replacement. You can find iinformation in these threads: http://986forum.com/forums/general-discussions/43017-carrera-gauge-swap.html http://rennlist.com/forums/boxster-and-boxster-s-986-forum/915925-programming-a-996-cluster-to-work-in-a-986-a.html http://www.boxa.net/forum/index.php?/topic/62435-how-to-upgrade-to-a-996-instrument-cluster/
  12. I did the same thing when I installed my Pioneer double din unit. Because the part is exposed to a lot of sun, I think mine became brittle. I may also be a little clumsy. I bought a replacement from Sunset Imports. The part number they quoted was 996-552-181-04-A03. The price was $24.32 in 2010. I think the "A03" is the color code for black. There is a guy in your area who sells parts from wrecked Porsches named John Wood. I would try him first to see if he can help you. Here's a link to a thread he has on the 986 Forum: http://986forum.com/forums/boxster-parts-sale-wanted/52469-parting-out-whole-lot-boxsters.html
  13. Check post # 13 on this thread: http://986forum.com/forums/general-discussions/51283-does-anyone-know-vss-wire-02-bose.html It shows a tip for removing one of the ventilation system ducts that makes moving the control easier. It also shows some photos that I took when I had my center console disassembled. I moved my controls down to make room for a double DIN navigation unit. Since the wire harness was long enough to move the control from the top to the bottom, I'm assuming that there is enough harness to move it the other way. Moving the cable up on the passenger side should be easier than on the drivers side. You will need to disconnect the connectors from the back of the unit, but when you look at it the technique should be obvious. There is also some good information in this tutorial: I think I may have the mounting hardware in my garage from the top position. Let me know if you are interested and I check my garage.
  14. http://www.renntech.org/forums/tutorials/article/153-yet-another-way-to-add-a-homelink-device/ I used this tutorial to add a Homelink to my 986. I realize that this uses a Homelink system from an older U.S. car, but it may provide some hints for your project. Good luck.
