1997 F-150 4.6.
I have a Check Eng. light (squirrels) - I've spliced all the wires (me thinks).
But now when I plug in my ODB module it won't connect to the ECU. Fuse is OK.
12 volts to pin 16 on ODB connector, Grd is good. The module is working on wife's car.
I'm now trying to remove the pass. kick panel and ohm the lines from connector to ECU plug.

Any suggestions? Thanks.
