hello I have put a 84 6.2 in my 89 suburban and got to the wiring part and I'm stumped what will I need to wire to my truck the motor has a harness on it I've got the glow plug figured out and I'll post some pics tomorrow sorry if this is a stupid question

 

Was this a gas truck? If so take the hot wire that ran to the distributer to the injection pump and if you have the glow plugs wired up every other sensor should be the same. The only thing I am not sure of is the fast idle I always left it off when converting form gas to diesel and held the throttle open for a minute and called it good.

 

yes it was a gas truck

 

ok im doing the same i have a 90 3500 and wanting to swap a 6.2 into it hard or not? will tranny bolt up? it has a 350 sb in it right now???

 

No it's not a hard swap. The trans will bolt up. You will need to put a diesel torque converter in it and you may need to change the governor.

 

governor?

 

Depends which trans it has in it but some of them need the governor changed to change the shift points. If it was me I would just change the torque converter and see how it drives.

 

i am looking for a 5spd and just change tranny and all not to keen on autos

 

The you just need a fly wheel and clutch.

 

thanks! ill post pics when its done maybe in the next two weeks
