Changed out heater core.. and now have a wiring problem!! HELP!

[90steelbluevette]

Hey everyone,

I am having a friend change out the heater core in my 90 Corvette. That is all taken care off now...

But there are 4 White mail connectors and 4 White Female connectors. They are all identically the same connector, however the wires are different colors/codes that do not match up to each other. We are baffled as to which one connects to what. So if anyone has any ideas, or knowledge please fill us in. I have the 6A electrical diagnosis manual and that is not helping us out.

Thanks!!!

Heater core reassembly.

When I replaced the core on my 90 I ran into the same problem. I only remember two males and two female connectors. You might take a look and make sure that there are 4 sets. If you get it narrowed down to two it won't fry anything if they are switched. So hook them up and check dash (gauges, lights, etc.) If the dash has problems switch the connectors and you should be good to go. I had mine hooked up backwards and it didn't fry anything. Everything worked fine when I finally got it hooked up properly.
