Harness Problem

Recommended Posts

Ok, I been having issues with my interior lights and other random stuff. I narrowed it down to the Porsche 986 996 Alarm Unit Immobilizer Wiring Harness. It seems the blk harness when its seated correctly it makes the dome light to faintly turn on but not a full strength. When I wiggled the harness and angled on the immobilizer unit it the lights came on full strength. I wiggled all the wires connected to the plastic piece and its not the wires as I can see. its the metal contacts inside the plastic piece. What is the next step, cause I found a harness for sale.. the question is it the immobilizer or wiring harness. My car is a 1997 boxster.<H2 class="vi-it-itSbHd"></H2>

its clean/dry and was cleaned already.. its not the Immobilizer , its the contacts in the harness. I just want to know if there is a way of opening the plastic pieces. The immobilizer is not the issue at all .. I just don't know If i should have the harness replaced.. All signs point to that is the case. The harness right now is on angle and the lights are works as we speak as I am seating in the passenger side of the car. So What can I spray in the harness plastic to clean it. I used nail polisher remover to clean the metal contacts on the immobilizer but I am not sure I able to clean in the tight area of the contacts in the harness plastic piece.

You most likely have corroded pins in the conectorsI usually, "fornicate" (for lack of a better word), the male and female plugs many times. That is, pull the female and mail plugs apart and put them back together repeatedly. This rubs off corrosion on the pins where it counts. This should only be a temp. fix but I've seldom had to touch them again. You ca also pull them apart and use a small brass wire-brush to clean them up.

I did everything I could and the plug still doesn't work. I ordered another one its used but its clean so I will have to connect all 11 wires. There is no other choice as I took it apart and its not working still.
