I have just reached the point of trying to drive my swap and i dont have any 4x4. the Truck is a 93 with a 3.0 original and the donor is a 2004 engine with a 99 harness and ecu. i dont have any idea on the vacuum lines so if someone could post pics or advise it would be really nice. i looked on here and didnt see anything that really helps me.
Thanks

 

Rather than deal with the VSVs, I simply replaced the axle flanges with Warn hubs (yeah, yeah, I got them brand new for cheap...) and routed a vacuum line to permanently engage the ADD actuator. I have to get out and lock the hubs if I want to use the 4 wheel drive, but no biggie.

 

i understand that i could take that route but i dont have and vacuum period. my cruise also runs on vacuum so i need to figure this out

 

how can you NOT have ANY vacuum?

Do you have power brakes?

 

I probably hooked it up wrong so im pleading dumb and need help

 

OOPs i feel dumb. never relized had to be hoked up on the plenum side of throttle body.
