I have a black 95 and i have a jaw wideband in it. The jaw works fine... and is the best 70 bucks i spent. Anyways, when i hook up the rpm signal from my computer (the black/ white wire 9th from the left on the 26 pin connector on the top.) The car wont work nor the tach... its like the JAW is stealing the tach signal. So should i ground the wideband to the ecu, by either using the ecu's ground or hooking in to the ground wire for the ecu its self, thats about the only thing i can think of. thanks.
