Has anyone had any luck trying to push the harness through the hole on the passenger side under the heater box? I’m trying to get mine separated so I can thin out the harness for my swap. The rubber grommet around the harness doesn’t seem to want to move. Maybe there’s a trick to get it out?

passenger side

should we guess on the vehicle you are working on?

Good point haha. 1986 S10 2wd. It had the 2.8 but I’m working on swapping in a 5.3. Non A/C if that means anything.

They're just gooed in good. Scrape off as much as you can so you can see what you're doing. Won't swear to it, but I seem to remember a couple sheet metal crews holding it in place until the engine side is bolted on.

I don’t remember seeing much goo on passenger side under the heater box where the harness passes through. There was goo on the drivers side at that plug though, but I was able to get it apart. I’m just hoping I can figure out how to push the passenger side through so I can strip the wires out I don’t think I need anymore a little cleaner. I’d rather de-pin the plug than just cut everything at the firewall if I can help it.

Have you looked inside under the heater core? there is a plastic horse shoe holding the grommet for the ECM wiring in the firewall
