On my reference sheet i got from astrochart it said (white)but that was for a 2.2 i thought and i have the 2.4.Well i did my searching and see that they say (violet/white)
so not being to sure i tested all the wires starting with the first one in the plug.I got to the yellow one and then did the violet/white and got the same reading.
so i asked the instruter and he said it didn't matter witch one of those wires i used.so i t-taped the yellow wire.
just want to know if i should change it and go to the (violet/white) are just keep it where it is.
i already solder'ed and spilt loomed it also
Heres what i mean by T-Tap
and the plug i tested
Got the same reading on the yellow and the violet/white,also found out that the inkectors have to wires comming from them and one 1 is common.
what year is the car?

The engine harness is found next to the battery, below the radiator hose, just above the transaxle.

You shouldn't be using a meter or probe on a tach wire. You could easily damage the ECU

You mean a test light my friend,a DMM is what your suppost to use
correct! ac scale. and if i had done a 2.4l i would know for sure. but that wiring info comes from audiovox. they and dei are THE last word in online wiring. but gm always uses white or purple or purple/white for tach. i have never seen a gm use anything else.

ok, dei says purple/white. but its not gonna be yellow. what i do is i print out audiovox and dei info for the car im doing. i try audiovox first, and if it doesnt program i use dei-if different.
you can tell in like 10 sec if it will program with the wire yer on. i dont pay too much mind to burning anything out as this is a "sense" wire. now a load wire, and POOF!
