Interior Wiring

[JamesCarGuy]

Hello everyone. My 1981 spider has been having some electrical issues and I've just decided to go ahead and deal with it now. I am starting with the interior and have my dash fully out of the car. I know most of the wiring will be fine because it is well protected from the elements but I need some help fixing known issues. I have heard whispers about the "brown wire problem" at the fuse box and ways to clean up the headlights which take up four slots and never get enough power? Also I don't have electric windows (phew) but my radio has not worked since I bought the car and while I am here I might as well give myself a nice upgrade. Im not sure of the limitations of the present stereo wiring and I am going to add extra speakers in the rear so any help if you know about aftermarket stereos is well appreciated. I have heard some people unplug the door chime and use that power for the radio so that it will save the ignition switch? Thanks for the help

Instead of the brown wire fix I installed a relay to the starter - and upgraded to the new starters. Great difference.
Not certain if you have relays to the headlights - if not suggest installing them. I had installed AR's headlight relays and they were simple and works great.
No idea on the radio - I am not using a mega watt blaster, though might sometime in the future. You can always talk to stereo installers.

But if you want to do the brown wire fix here is the website.

+1 on both of the last posts.

+1 on above, and add relays for the wipers......made a huge difference. I did the headlights and the wipers and also installed LEDs in the dash lights. all recommended.

The relay idea sounds good to me and I do have a new gear reduction starter to install to be safe. I will get a buddy of mine to help me out with the stereo since he has done some to his cars. Thanks a bunch for the advice
