Replacing main wiring harness

Recommended Posts

Hello everybody, I have bought a (interior) totaled 1998 porsche boxster. I will be putting in a complete new interior wiring harness into the car and tried to find info about it in the porsche workshop manual (the original). But I could'nt find any information about routing the harness properly. Nor was I able to find anything about the firewall behind the dashboard. The thing is that the interior is completely stripped down(picture). So, I need to rebuild it from scratch. I thought the best way to start is to put in first the firewall, after that the a/c unit and then the dashframe and wiring harness. Could anyone please help me? Any advice is very welcome! I can imagine, you would all give the advice not to do this project, please don't. I need to maintain motivated, cause there is no way back! :unsure: I hope you could help me with this. Thanks in advance!

I hope you have a lot of experience in this area or you probably wouldn''t have pursued such a huge undertaking. Buy a car of the same year and disassemble it to the point that you can use if for a guide. Wire routing is often not intuitive and a guide or manual must be used to get it right. I have been involved in enough simular projects to know what you are facing. Good luck with your new hobby.

But could you tell me what guide I need or where I can get it?

There is no guide or instructions. Porsche makes a custom harness for each car depending on it's ordered options. When a Porsche service tech orders a harness for a car he must specify the options - wait several weeks, then replace the original one step at a time. Needless to say very few Porsche service techs have done this.
