Aristo 2JZGTE Harness problems

[DETONATION666]

Me and a friend were taking a harness of an aristo motor I just got and no matter how carefull we were they kept on breaking and snaping like the plastic was brittle as hell?
A friend of mine suggested that the motor might have been overheated and that could have caused the harness to be like that?
is that a common problem?

It's an old harness, that sat on an engine in a junkyard for many years. Its common to see that. Best way to a 2jz swap is to use a new US harness.

heat + plastic = brittle plastic. it depends on where the plugs are to see if they are common but more likely than not they are very common, in both jz swaps ive replaced all the coil plugs for one!

curious how much a new US harness was?
but it was about 150$-200$ for new plugs they arent too much and the wires were good only the coil packs were brittle in any way

6spd harness is ~ 850 iirc

not cheap but easier then putting new clips on all of the place
I was really pissed though I figured I could use the harness it came with

if you get a new US spec harness, wouldn't it be different cause of the MAP vs. MAF

i think a guy on SF had a list of all the plugs on the harness with part numbers.

yea...when i bought my us 2jz the harness was breaking and snaping too. i just buy a harness from toyota dealer $449 for a new us harness. i believe the us harness is a liitle different
