So I just upgraded my torque converter to a 2600 stall and installed summit plastic race seats in place of my power seats.

I test drove it tonight, and all of my accessories and headlights shut off when I got on it and let off.

I pulled into a parking lot as the car still ran fine, Window motors still work, etc. Pretty much anything off the key works, but not headlights, radio, etc.

So my theory is, I forgot to tape or remove the harness that plugged into the power seat motor. I think it may have shorted on the underside of the seat.

I checked the fuses in the parking lot in low light and they looked fine. Where should I check next?

 

Ok so after doing some research, I don't think it is the headlight switch because the radio also stopped working. I am wondering if it is a fusable link, does this sound possible? If so, could someone help me in locating the fusable link for these devices on a 1989 Iroc Z? Is it near the master cylinder?

Thanks

 

So if I wiggle the harness under the dash that goes through the firewall, all the accessories work again. Is this a fusable link or something else? I never would have guessed but I came across this link while searching:

Thank you sir!
