Thanks RF for the pictures. I did pull the 3 relays off the strut tower on a cady. 2 are Bosch and 1 is ?.
Do have a part number for a AC Delco 4 wire 02 sensor?
I will be getting an adaptor plate for the TBI and that should help with the install.
The 31 gallon fuel tank was way to big for my 4x4 rig so I found a 25 gallon one from a 87 Blazer. Should work great.
Will keep ypu all posted.
