Gen 2 ?

[GBGN1]

I've got a quick ?, my car has an issue running with the gen2 plugged in. I notice on the sm that without the gen2 plugged in the tps is .42 volts and when plugged in it is at 3.98 . I can move tps and it doesn't change with gen 2 plugged in. Any thoughts??

wiring problem?

I'm going though it now, I installed a ccci harness from caspers at the same time.

Hey bob is grey wire used with the gen 2, did the hook up in the dark and hooked it to the tps signal . That took care of it . It says its for voltage signal 2, is this used??
Thanks

gray is not used, connect the blue to TPS.

all 3.5" aluminum MAFs are extremely similar, so either the 3.5" LT1, or LS1 aluminum setting should work fine.
