Steering column extra black ground wire to column?
During my weekend project I removed the steering column to make some repairs -(and pull the brake booster), I bought a new multi-function switch from AC Delco. It is identical to the one that is in the car except there is an extra black wire in the cars ignition switch harness- it is a black wire that grounds to the steering column. It looks factory, the new Delco harness is a blank pin there. Anyone know, what that's about? Is is a 90 only ground for the airbag?

that black wire has nothing to do with the AIR BAG to my knowledge..

Re: Steering column extra black ground wire to column?
I'd think you can ignore the D in the harness. If you wanted to do something with it (the pig-tail ground) you could splice to the G in the harness. I'd think it's intention on column) originally is for the 'horn brush'.
See 8A40-0 in the FSM. Is D on the mating connector populated? If yes just move it from your old and swap. Last edited by WVZR-1; 03-04-2020 at 08:50 AM. |

Release should be very straight forward. PCK-CON Male.png If you've a GM Dealer close and they have the GM Terminal Kit. Most should - get a Delphi 12020320. Tell dealer it's in Tray #1 if they have the J-38125 kit. Last edited by WVZR-1; 03-04-2020 at 04:37 PM. |
