So I have replaces the clips going to the coils already and I know one going into the maf the clip is broken. I had the wire get loose on my Knock sensor and need to replace that. So i was wondering if there is a way to just buy a brand new wire harness so I dont keep replacing broken or damaged clips. Thanks in advance.

 

I am assuming i found it as part number 82121-3A360. I found this off a ebay search. It is 250 used on ebay but probably have the same issue too soon. I have found it for $550 on the web. Anyone know a cheaper place to get one?

 

If you have a part number you can try sewell lexus the help out forum members.

 

A used harness is gonna likely have the same issues, most all the coil pack connectors are always cracked on every 2jz I've seen. The coil pack cover just hold all that heat in there between the valve covers. the knock sensors mounted directly to the block get hot as well. But for the most part those are the main two problem areas.

Honestly I would just get the connectors are repair them, a new harness is a huge pain to install, and any used one is almost guaranteed to have a few cracked connectors somewhere on it, I've never seen one that didn't..

 

Does anyone know a list of part numbers for the connectors for easy referance?

 

All the connectors use 90980 as the first half of the part number, some connectors have it on them, but some don't. If you only see a 5 digit number on the connector this is the case.

For instance the coil pack connectors have 11246 on them. So the number to order is 90980-11246..

I had a chart of most all the connectors, if I can find it I will post it up.

 

Here is a huge factory document for a supra, but most of it will apply to the GS 2jz.. It covers dissasembling the connectors, repairing damaged wiring, and has dozens and dozens of pages of connector charts so you can match up what your connector looks like and has the full toyota part number for each.

This should be all you need to fix anything in your harness.

Thanks! This thing has a lot of connectors. So I guess when I get home i will be scrolling threw it again with the connector next to the monitor. Hope I match it right. Too bad someone don't have a list with the name of the connector and part number. But this should help alot so thanks!

 

This reminds me of the notorious s600 w140 i had back in the days, the engine wire harness on those were pathetic
