Goals -
1) populate Pin71 (Horn circuit) & provide connection to horn circuit in 'OEM-like' manner.
2) Fool airbag diagnostics to prevent fault code / warning light.
Rules -
1) do no harm - no cutting of underdash harness or hokey wiring that can fail, short, or cause future headaches.
Solutions -
1) obtain mating connectors from Porsche salvage yard (Oklahoma Foreign was accommodating & helpful)
2) obtain 2.8ohm resistor to mimic airbag
3) make jumper harnesses as below:
Parts:
Airbag control module diagnostic foolery:
Horn wiring jumper harness (brown-only wire is the original ground, don't have the correct tools to de-pin these yet so it will wait as is):
Soldered & heat shrinked (use a glob of liquid electrical tape underneath heatshrink to keep moisture out):
Pin71 again - if you'd rather be 'creative', splice Pin71 to the brown wire w/ white stripe via any means possible. You've been warned though..
Populated into connector:
From the mating side:
plugged in (brown-only wire is the original ground, don't have the correct tools to de-pin these yet so it will wait as is):
Loosely secured with zip-tie:
Installation is the reverse of removal:
