Well I’m installing a LGX. had it all wired up and running. Then connected back up lights. Tone gear for rpms oil pressure switch temp switch. Had it all working through GM ECU and Mazda pcm. Then got brave connected the coolant level light.
next was the oil level from Mazda to terminate with GM. I shorted something in the Mazda side at the pcm extra wires. Now the Mazda when turned on no fuel pump. Over to start and no start relay power.
can take start relay coil ground to ground it starts. Fuel relay have to jump power to one of the main wires to run fuel.
need direction. Checked all normal grounding areas.

 

Got the Mazda wiring fixed. Now have the low coolant and low oil level connected to the car dash. LGX IS running but been chasing wire issue from pedal and throttle intake to ECU. think I have that now. But not getting correct control. Rough idle and 4,000 rpm max. Rear is up on stands and I’ve run the gears up to 86 mph at 4,000 rpms. Now to HP tuner to see what’s wrong or missing or needs fixing.
