Hey guys another question, I got the gas pedal from the LBZ truck but it doesn't fit on the studs that are there so did you guys just drill it onto the plate?

Ok just want to clarify on the wiring, so I used the wiring harness from the LB7 that goes to the fuse block and from there to the engine stuff and down to the transmission. Is this the C100? If it is do I still need to move G(TN) to J? I did use the LB7 fuse block as well so you mentioned I didn't have to worry about moving the orange wire on C2 so I was wondering if this is the same for C100? Lastly for the Add a wire to F & G for the GM LAN (+/-) to the OBD Connector, where do these come from?

You used the LB7 harness and fuse block, or is that a typo?

I believe the C100 is the one I am holding, in this pic. If I understand Russ correctly.

So I am guessing if I used the harness from the LBZ which has that C100 you are holding in the picture I don't have to make any pin changes from G to J right? I am a little confused about the F & G for the GM LAN though.

Hi, I just did the swap from LB7 to the LBZ and I got everything put back together. It will start and run for a couple seconds then it shuts off. I did the VATS relearn and then did the VATS bypass and it still does the same thing. I double checked the wiring and everything is good accept maybe the purple wire for the tap shift, I used the steering column from the LBZ so it had all the wiring but I wasn't sure if a wire still needed to be run from the fuse box to the interior for the tap shift. Any help or suggestions would be great!!!

Thanks

Dan
