1fz-fe wiring harness (1 Viewer)

[Darkdragon]

While removing my harness to do a head gasket job, i was careful enough to not break any of the 25 year old brittle connectors of course until i got to the last one.

my questions are

has anyone tried to “rebuild” the harness with new connectors?
if so where did you purchase the new connectors?

thanks in advance for your help

I just did the same, but only replaced the injector housing clips, all 6 of them. If I were to do it all over, I'd replace the whole harness, but my vehicle is relatively low mileage.

I'd get a new harness, Heat shield wrap the important parts near the EGR valve area, all the way back on the back firewall. Then tesa tape the whole harness and be done. The time you saved will be worth it. Not sure how much they are these days.

Darkdragon, below is a link to a factory service manual that has the part numbers for every connector on your Land Cruiser. Plus it outlines the correct factory/Toyota way to repair your wiring harness. So you may want to book mark this page.​

Thanks for the advice. Im going to get a new harness and eventually rebuild the old one.
