Doing the H/G on my 22rec, got the intake chamber pulled, but the "ECU wire harness" runs through the middle of the intake manifold (to the starter, etc). I don't see instructions on unwiring all these hard-to-reach bits in the FSM, so I'm wondering if there's another way around this.

Anyone got suggestions on avoiding unplugging another 10 wires, this time in hard to reach places?

I can see from this photo that I'm not the only 22re that has the harness routed through the middle of the intake manifold (is this the proper place to thread it?):


tnx, Seth

 

I can tell you that ive had my intake off twice,and yes,thats the way its run.you can reach a few of them through the rt wheelwell with the tire off. just keep markin n pullin!! good luck.

 

yeah the harness runs down through the lower intake manifold, plugs into the knock sensor, oil pressure sensor, and starter solenoid, and then goes further back over the transmission where you'll find 3 (if I'm not mistaken) plugs on the transmission, and then another for the O2 sensor


it's about a 5 ft long harness once you get it all unplugged and pulled out


they're all like that; it's how it's suppose to be... kind of a ridiculous way to route it if you ask me, but eh, it works I guess...

 

thanks ya'll, I pushed through it and am now looking at the rocker arms, valve springs etc. here comes the fun part! :-P

 

Yeah, thats the way we (me and a buddy did it) what a pita that was! We also stripped a allen head bolt on the intake and had to pull it off with the head.

Any thoughts to not putting it back thru the manifold?

 

That O2 sensor wire is a bugger, at least on the 3VZE.

 

I guess you could reroute it but then you have the problem of trying to plug in the connectors for the injectors. With the upper intake manifold in place.

I have a hard enough problem getting those clips off when I can see them.

Another problem is I am sure some of the harness would need to be lengthened.

 

yea when i took out my injectors to get serviced the connector pieces kinda just crombled. so now im looking to replace it all. oh fun. but it now takes me about 15-20 mins to take off my air intake
