Warren’s Conversion - Difficulty Removing Wiring Harness


 

Friends,
?
I have had considerable difficult removing my wiring harness. ?I cut out a portion of my rear Westy seat box but still couldn’t get the connector through the hole, so I snipped it off and pulled the wiring into the engine bay. ?I posted the following on the samba so I thought I would post it here as well as I try to get some guidance on removing the harness. ?One kind samba member has responded so far and provided a photo (many thanks 4Gears4Tires!!). ?
?
Okay guys. I’m not sure how to pull the Vanagon wiring harness, i.e., what to take out and what to leave behind. I removed the ECU and pulled the main harness back into the engine bay and started to try to figure out what was what.

There is apparently a main harness and an engine management harness. I should remove the engine management harness but I don’t know the difference. I asked for help from Jeff at AVSubaruconversions, who did my wiring harness, and indicated that I am a visual person and asked if he had any photos. He said “I don’t have any photos. To do a swap you need to be familiar with both platforms” and eventually told me “you need to know what you’re dealing with and looking at to do a swap. At this point you would have to research or pay somebody that knows how to do a swap if you don’t want to research.”

The mechanicals are easy for me. The electrics are not.

So I’m doing research as Jeff suggested and asking for help! What to take out and what to leave behind? When I received my harness Jeff included some notes and a screenshot of Smallcar’s diagram to connect to the black box. So I feel confident that when I get to that point I will be able to install the modified harness. But I need to get to that point.

Any help, photos, diagrams, etc. will be appreciated. Thanks in advance!”

Morning Warren.
I’m not sure if this will be helpful but it’s a page from Mr. Shiel’s online guidance……


Best of luck,
Brent

Re: '90 Auto Westy
When I removed the harness, I unplugged the ECU, moved the backseat forward and was able to push the harness and grommet through the firewall hole. Then I unplugged and disconnected all connectors in the engine bay. I left the black box in place to splice into.?

Thank you Wayne, Brent, and Nestor, and 4Gears4Tires, and others
?
The photos helped immensely. And those photos from Tom Shiels’ website were really valuable although I’m not sure the ‘86 wiring is the same as ‘87 onward. ?I finally figured out that the wiring bundle that went to the passenger side tail light area was for the idle stabilizer unit, so I pulled it out. ?The only thing connecting the wiring harness to anything right now is the connector with green wires coming out both sides. ?One side is in the harness, the other goes up the wires to the black box. ?Not sure how to proceed with this one, but at least I’m this close to getting it out!

Again, many thanks!
