I'm asking this before I start trouble shooting hoping someone might know something that will save me some time
I'm doing an swap into a gas w250.
Ok I put a 91.5 d250 cummins engine bay wire harness in a 90 W250 gas truck.
I left the steering column from the 90' in and also the harness connection point (where you bolt the harness into the firewall).
But I get nothing when I turn the key.
So my question is do have a compatibility issue between the engine bay cummins harness and the firewall-back gas truck harness?
