Advice needed..

[Black Beauty]

I have an 85 k20 that by the grace of something or other very fortunate that I haven’t caught fire. The original fuse block was melted together and pretty much shot. Pulled the old under dash harness out and went to the junk yard and got one that was in pretty decent condition. I swapped all the connections over to the good one and now am at a bit of a stuck point. Someone wired up a aftermarket water temp gauge and it works but since I’m putting stuff back to the way it was I’d like it to feed to the dash like it did from factory. I have a few circuit maps but I just don’t understand how to read them I guess. I took the gauge cluster apart and the printed circuit was on its last leg too so I have one of those on order should be here tomorrow. So here are my questions...

1. Where does the water temp gauge need to feed into for it to read of the gauge cluster?

2. Can someone show me a picture of their fuse block where all the proper fuses are? I didn’t take a picture before I started tearing things apart.

If you ran all the wires back factory, then the gauge should just need the sender.

So what you wanna know is where under the dash is the plug for water temp?

I guess. I’m not anywhere close to an electrician. I guess my question to clarify is which wires go where.

Had you asked yesterday I had the whole fus box and stuff out for burnt wires.

I am sorry man. If you dont get it figured out. I will pull it again, and take pics for you.

Gotta spend my up time installing relays for my fans now.

They aren’t factory wires coming from the temp sensor. That’s why I’m kinda lost

Sorry man. Wiring is not my fortay, I will tackle it first hand, but pics do me no good at all, I have to trace, and use my multimeter/test light.

Google will be your friend here. Lots of searching through pics for those particular plugs.

Sorry man, I absolutely wish I could help you more.

Just telling you what I would do.

Lots of google searching for those plugs, with wire tracing.

Thats how I get alot mine done.

Looks like Brake Lights (above) and 'Cruise' in the middle.
Can't even guess the bottom 2.

Pretty sure those are for the cruise control and wiring related to the lockup torque converter. The connector with the masking tape locks like it would clip onto one of the brake switches.

Like Roger and Matt suggest, the connector in the first image looks like the one used for the brake lights switch:

Problem is that while the ORN wire is correct, the other one should be WHT. Also that green wire (or whatever color it is - I'm color blind) appears to be a bigger gauge than it should be. You might want to trace it back and see if it is spliced onto the WHT wire that goes up to the multi function switch in the steering column.

Where did you get this? I want, I want. Please tell me how/where to find the rest of this.
