joe_padavano I don't think the 1995 trucks used the PASSLOCK anti-theft system, but you might want to verify that.

EOD Guy My bro-in-law just completed a simular swap....... his Ing module fried, it's the thing next to the coil that the wire harness plugs into.

LATECH without having schematics for BOTH trucks you may not figure it out.I would look for both.
My guess is there is differences in the connectors / wire / pins... at the ECM between the 2.

LATECH check your installation job for missing grounds. Then verify power at the proper terminals in the ecm. BE SURE to probe the harness with the connector unplugged to avoid probing the wrong terminal and cooking something. There shoould be 1 or 2 power wires, maybe even 3, one allways hot and 1 or 2 that are switched, I dont have the schematic in front of me or I would coach you through it. Get one and check the approriate terminals.
Post your results.Peace.
