[Diy_efi] 4L80E into 6.2 diesel application

[Eric Deslauriers]

I think the following is what I need. Thoughts?


Looking at a '92 C2500 wiring diagram for the TCM, this is what I think I
need:

Need
=======
TCM
wiring harness
Barometric press. sensor
TPS
Engine speed sensor
Input Speed Sensor
Output Speed Sensor
VSS Buffer [DRAC]
ALDL connector for seperate interface from existing ALDL connector
RWAL diode MOD <--what is this?
..Rear wheel anti-lock, perhaps? ignorable?
cold advance solenoid

Parts I already have on my 83 motorhome I can reuse
-------
NOTE: the 3 following seem to be on their own circuit anyways. Right?
..fast idle sol
..fast idle temp sw
..water in fuel sensor

NO need
--------
Fuel relay [could use]
fuel pump [could use, already have aftermarket]
fuel heater
