I've been working on wiring up my cab and fan controller. They are pretty close to complete. Truck starts and idles great. Here is a picture of the gauges installed. For the time being I'm going with the clear coat over rust look.
I do have a couple gremlins I'm hoping to get help with though:
1) I don't appear to have any tach signal coming from the PCM wire. Does anyone know any diagnostics for that?
2) PCM is throwing a P0068 Code which is a conflict between MAF Sensor/Throttle Position Sensor/MAP sensor (this truck is drive by wire). Also, this might be related, but I have a bit of a lag between when I stab the throttle at idle and when it speeds up.
Any input will be greatly appreciated.
