I've recently bought used but not sliced headlights harness and wanted to replace it today, i've managed to disconnect alllights and indicators but when i wanted to disconnect connector:



i failed, how in the world should i disconect it ??

also this harness has this connector, what is it for ??





best regards

 

The little round one is for the brake pressure switch in the proportioning valve.

The other one, you'll NEED to disconnect the battery for. You see that big black block of wires attached to the firewall by the brake booster? That's the left third of it. You'll need to use a 1/4" socket and unbolt the middle of the connector until it pops loose, and then when you get the C100 separated from the inside half, you need to squeeze the tabs on the lighting harness connector and push it towards the TERMINAL side of the unit to release it, and then pull it out a little so you can slide the harness out the gap between the legs on the engine part of the harness.
