2007 LBZ into 2005 LLY

[361ddm]

Installing a 2007 LBZ with 6 spd tran into 2005 LLY w 5 spd.

I have the compete 2007 donor truck. Need help adapting the 2007 eng / chasis wiring harness to the 2005 Cab wiring harness.

Any help?

Thanks !

Lly to Lbz conversion issies.

Ok so this will be lengthy, as I will go into details about my swap so everyone knows what i did. It started off that i purchased a Regular cab long bed 4x4 06 lbz from evan about 2 months ago. The plan for it was to take the engine/trans/ecm and tcm controllers and harness and put them in my...

Basically, you're swapping everything under the hood from the LBZ truck to the LLY. Swap throttle pedal, cluster, shifter. Repin a couple wires.
