Yes I have read all the threads about how to use it and where it SHOULD be located. I have searched the inside of the fenders near the firewall high and low, following the the wiring harness, etc. I did find two connectors hooked behind the fuse panel on some retaining clips that have 3 pins each, one grey one black, but nothing that matches the pics and discriptions I have found. Now the wiring harness is far from unmolested, the previous owner has spliced and hacked to high heaven. I have kind of figured it got hacked off. Any other suggestions?

Picked the truck up for $500 bucks and im starting to tear into fixing it up. its an 87 f150 ext cab w/ 351 and someone slapped a 4 barrel Holley on it.

Thanks in advance

 

Good luck. In 87 im 99% sure the 351W trucks came carbed from the factory...

Otherwise it will be under a cover bolted to the back side of your airbox. will say EEC TEST PORT on it.

 

Yah ... thats what I thought ... its gone

Thanks for the pic ...

 

In 87 the 351w came stock with the 4bbl holly and no obd1. the 351w did not go EFI tell 88. I love my 87!

 

Good info ... thanks...
