Tested all 3 wires to LDP & orange wire shows nothing. Did resistance test from pcm connector to LDP connector on orange wire & checks good with load. PCM ? what's your thoughts? White wire with green stripe is grounded with LDP turned on with scan tool & white / blue stripe has battery voltage.

*FIXED* So i had a brain malfunction yesterday testing this circuit. I misread schematic. Was thinking orange wire to LDP was control wire & it was white / green stripe. I discovered someone had replaced clutch master cylinder & pinched white / green wire (control) between firewall & master (grounding wire). Momma said there would be days like this!!!

By the way anyone interested control wire is suppose to pulse signal not steady ground.
