Need help identifying where a black clip coming from the passenger side fire wall with black, grey
& Brown wires is connected to, almost finish my heater core job and this is the last thing I'm having trouble with. Any help will be appreciated .

 

What year? You might try browsing google images and/or Ebay for dealer ads which sometimes have good engine pics.

 

Was the job a bear? I started smelling a little coolant when I run the heater the other day.

not looking forward to it at all.

 

The job is a bear though it's simple. Theirs no requirements to measure, set specs, use special tools etc... Their's lots of bolts, wire connectors, and a need to move parts with care. There's good how to's on this site. One thing I read somewhere which was a huge help was the tip to drill a hole in the engine compartment Black Pastic cover which shields the bolt near the screen. I tried to get a wrench on it and it was a pain. I measured the distance to the bolt and put a 1" hole in the cover and I was then able to remove the bolt in a minute using a socket on an extension. The job might also require having new insulation for the heater core on hand. I used the 3/4" AC insulation available at Lowes.

 

It's a 1998, sorry I should if been more specific the clip I'm talking about is actually by the main harness underneath the glove compartment close to firewall. I'm going to try to post up some pictures later.
The job wasn't really that difficult just make sure u take pictures of everything u take off and label the screws , bolts ect so the same thing that happen to me won't happen to you

 

here goes a picture of the clip

 

Flux Capacitor??

I havent tore through my dash in the blazer, but it kinda looks like the speaker wiring harness in my old car...
