996/986 wiring troubles


Recommended Posts

Hi, I need some assistance and not sure who to go to post in the 996 or 986 forum. I have done lots of searching around but can't really find my answer. I am trying to replace my stock 97 986 head unit, speakers and amp. I have all the seperate components purchased already and everything taken apart in the car. My problem is the wiring. I don't know how ot go about it. It looks like it will be too hard for me to run new speaker wires to the doors (am i correct?).

I also don't know how to wire the new HU to the stock CD210 harness. I bought a Scoshce Harness for a 97 996 but it doesn't seem to be the right fit. I dont have the BOSE system in my car. I heard that a VW harness might work? Any ideas or can anyone point me in the right direction for a wiring diagram of the stock wires so that if I can't find a harness I can just hard wire to the stock wires myself? Thanks any help would be much appreciated.

I have already run RCAs and power wires to the front trunk without problems.

drive your car down to Seattle ! I'll do the install for u ,,, haha

was ur stock head cr220? I usually hard- wire mine, never seen/used one of those hardness .

Step 1 head unit

If I was doing this job ,,, would start with installing the head unit. All u need is 3 wires from your cr220

#4 contact - permanent 12+ , #7 contact - switched 12+, #8 contact - ground , new unit should be up & running

Step 2 speakers

And yes, it is extremely difficult to run new door wires but it can be done,,, if u were equipped with an old stock amp (HAES), existing speaker wires will be at the front trunk, where you will need tap all 4channels.

Step 3 amplifier

Good thing! U already have those cables ran. It is very important U use a high quality RCA cable, also to run a pair of proper sized power cable(oxygen free)!

You will also need a remote wire, u dont want your amp to be running when the car is not on.

Hi juniinc,

where did you run the wires from the back part of the trunk (whre the battery is located) to the front part of the trunk to the amplifier?

I could run the wires very easily from the head unit to back part part through the hole behind the battery! However I can not find a suitable place to run to the amplifier!

Thanks, Marco

P.S. It will be different between Boxster and a 4wheel Carrera. I need a routing for a 4S!

any time ,man

Thank you, I did it that way!

However, this was not a blind plug in my car. There run cables for the Litronic/Xenon lights regulation! But there was still enough space.

Thanks again!
