Happy you are finding my info useful. Ed B

I reviewed the wireing diagram for the '97 Tip and it appears it would be possible to add factory cruise. You need to determine if the control unit for cruise control is already on your car. It's located "above footwell outlet nozzle" near the steering column. If it's there you will have to determine how much of the wireing is there. The '97 is quite a bit different from the '00 and later models. You will need the wireing diagram. The PET shows the control unit, (in the steering section), and the P/N varies with the year. It does not show the option code, M454, so I'm assuming it's installed on all cars. Good luck. Ed :thumbup:

Subject: Adding Boxster Cruise Control w/E-gas CORRECTED 11/08/03 It is possible to add factory cruise control to a 2000 E-gas Boxster. It helps to have the factory wireing diagrams. The wiring is slightly different on a 2.7 and a 3.2 S. It's best done with the top partially open. You will need the 3- or 4-stalk unit. ( P/N 996 613 219 10 EWC for the 4-stalk unit) and a 999 652 972 40 connector. You will also need some of the female pins for the ends of the wires since the connector doesn't come with them. You will need some for the Motronic connections too, so buy about 12 . (I don't have the P/N for the pins). This is a good time to install the OBC if you don't have it as the 4-stalk unit is cheaper than the 3-stalk. Follow the directions for installing the OBC in regards to the steering wheel/ airbag/ instrument cluster removal and stalk unit installation. (Use Google and search for D2 Performance) You will also have to remove the left kick panel. Pop off the fuse box cover. Remove the 4 phillips head screws and the panel will come off. The cruise switch has a 4-unit connector: #1 black goes to Motronic connector IV pin 27 #4 brown/yellow goes to Motronic connector IV pin 19 #3 yellow goes to Motronic connector IV pin 25 #2 black goes to fuse B7 You will need to run 4 wires to the Motronic unit in the rear trunk (#1, #3, #4 from the cruise switch) and one from the instrument panel connector III pin 17 (black) "S". ( connector I pin 16 (blue) 2.7). to Motronic connector IV pin 18. Run a wire from #2 on the cruise control connector to the rear of the fuse panel at fuse B7. I used a modified quick disconnect at the back of the panel. The panel back can be accessed by squeezing the clips and laying the panel flat. You will need 4 wires about 12 feet long to run from the stalk unit to the Motronic unit located in the rear trunk on the left side. The motronic unit has five connectors. # 1 has 9 pins # 2 " 24 " # 3 " 52 " # 4 " 40 " # 5 " 9 " I taped the wires together to make it easier to fish them through the chassis. Run them from the stalk unit down the left side harness along the fuse panel. Next remove the hood and trunk release mechanisms. There are 3 plastic plugs; pop them off. Use a 5mm hex wrench to loosen the bolts about 3-4 turns; do not remove them. The unit will snap up and out of the way. Don't remove the cables. There will be enough room to run the wires next to the existing ones. Also remove the rear side panel just behind the door. One phillips screw at the bottom hidden in the carpet and one hex head bolt (8mm wrench) at the top near the roof hinge, loosen do not remove. Remove the trunk liner to access the motronic unit. The fasteners snap out. Run the wires up along the existing ones. I found it impossible to run them through the wire chase above the rear fenders, so I ran them under the black foam panel in the top well and through an opening into the rear trunk. Don't block the hole in the foam -- this is a water drain. Install the connector pins on the ends ofthe wires and insert them in the proper holes in the connectors on the stalk and the 40-pin unit on the Motronic unit. Replace the instrument cluster, fuse panel, kick panel, rear side panel, trunk liners, etc. Visit your dealer to have the cruise control activated. Cost me one hour labor. Enjoy! I can send the following photos if anyone wants them. Fig1: Rear wiring harness closeup - dark rubber foam. Run wires under rubber foam at top. Fig2: Wiring harness - left rear trunk. Motronic unit is just to the right. Fig3: Connectors with instrument cluster removed. Fig4: Wiring harness at fuse box. Fig5: Wiring harness on left rear quarter panel. :rolleyes:
