91 Rs lo3 wiring headache

HEy guys looking for some help and/or advice. basically trying to save this car and get everything working again. Previous owner halfway deleted a bunch of stuff so im slowly putting her back together the right way.

Had an instrument cluster issue and when i pulled it out i noticed all the hvac ducting was missing and the heater box wasn't hooked up right. Come to find out the whole hvac system was halfway deleted and for some reason had a heater box in it from a all cable driven control head. Older model i think. but the recirculation flab was patched with clear silicone and a license plate :/.

So after pulling the dash and many trips to the junkyard to try to get everything around i needed we are kinda scratching our heads at some of this wiring. I'm not going to lie guys i love this car. ive always wanted a third gen my whole life but this car has got me so frustrated. So on to the wiring issues im having. My washer pump isnt getting juice for some reason? but when i turn the multifunction lever the wipers act as if the washer pump was squirting. My inner two headlights are also not working for whatever reason. My horn doesn't work either. And lastly my rear hatch switch only makes a clicking noise under the console nothing more. But those problems can probably wait until after i get the dash put back together? Right now some open connectors are making me worry. And maybe some of them might be the culprit to my problems.

There are some connectors idk where to put.


This one I have no idea what it goes to?



This wire im pretty sure goes to the pass side door jam switch because there is no wire going to the switch now. I'm kindof confused though because the drivers side switch has two wires going to it and this side has only one? Is that right?



This one come out of the harness about the same place as the headlight switch. again no idea.



This one it up underneath the dash on the drivers side. Looks to me that maybe a relay is supposed to be in it? any ideas?



then there is this little guy come out right in front of the heater box. Too short to really go anywhere besides where the radio/control head goes?


ok then there is this here. I think its a light? where does that go? Once again it looks like it can't reach far? maybe into the underdash panel or radio/control head area?

Thanks for any help in advance guys.

Re: 91 Rs lo3 wiring headache

another update guys. seems that the first picture up there is of a harness no one has found a use for. i founjd another thread about it and same thing inconclusive but no wiring issues without it. i also found a wiring diagram that shows that the red blue wire from the washer motor goes to the wiper motor? i think i read the daigram right. but i know i have power to my wipers so im gunna try n narrow down that tommorow. still wondering about the one that looks like a relay plugs to it. also the little yellow light looking one and the one wire connector up there. anything you guys know would be apreciated.

Re: 91 Rs lo3 wiring headache

ok so thanks for the feedback guys. i have studied the wiring diagrams pretty thoroughly and as you can see i found a few of them using it. Coldwater is about ten min north of indiana off I69 in the heart of branch county. and nope my buddies last name is clark. Actually just traded that fox body up for an 84 vette. We've been having fun with that lol. and hoogies thanks for the help.
i found another thread about number #1 and it was also inconclusive. But they did say they left it unhooked and havnt found any wiring issues yet...?

#5 has got me worrying a little but not much. thats one i havnt really looked for yet in the diagram. ill prolly do that now and let you know what i find.

#4 i was really wondering about so kudos to hoogie for helping with that! my camaro didnt come with fog lights so that would explain it.

#6 still wondering what that lights up but maybe ill figure it out as it comes together?

Re: 91 Rs lo3 wiring headache

ok so i found a single grey wire in the diagran and it says its fog light switch illumination? doesn't seem to come out of the harness at the right place for that though. Im thinking maybe the two wire harness and that one wire were for the cars that had the little clock option maybe? didnt some of these cars come with a little clock to the right of the steering wheel or am i wrong?
