have question about transmission wiring for 6.0 swap to a 98 suburban

[98 4X4 burban]

thanks again for the pinouts for the ls1 but i am still stumped. i think i might have gotten over my head but it is too late to turn back now. i just talked to a buddy of mine on the phone that used to work at TRT and he told me you you know your stuff.

can i use the 6.0 harness to run the engine and tranny functions?
lf so do how do i make the push button 4X4 and gauges work? i just went and bought a chinton manual for the 89 as well as the 2001 i think i have it figured out but i do not want to mess any thing up.

thanks again and any extra help would be great

i would like to get more info myself.
i purchased a complete, i mean complete 2006 motor and trans.
for my 97 and i have the motor mounts etc, im really ready to set it in.
but i just need to know if i could just use my 2006 harness and just zip tie or whatever my 97 harness and just set it out of the way?
my 2006 has EVERYTHING gas tank included

i did alot more digging and looking for info on this swap after i posted this.
i was going to run 2 harnesses and pcm's but the more i looked into it i was going to have to cut and tie into the factory harness to make everything work so i just pulled what i needed out of the 98 harness and trashed the rest. i dont know about the 97 but on my 98 about 99% of the wire colors and circuit numbers are the same from 98 to 2001 (my 6.0 came out of an 01)
i am doing the wiring myself but if i had to do it again i would send both harnesses to someone and have them converted.

cool cool.
i will be sending my harness to Spear Tech. I really like dealing with John over there at spear tech. he is very very helpful.
i have a 06 complete 5.3 motor trans wiring cpu etc etc.
John said to send him my harness and for 450 he can cut out whats not needed for my truck and add the iac and the tps wires for the cable driven throttle body.
i have to purchase the throttle body and i will be purchasing a return style fuel rails also for the 06 motor.
also i have a 411 ecm he said he would swap it out for the 04 gto ecm so it will work with my 06 harness.
i have tried to get that kind of info from others and its like TOP SECRET, just send me your money is all i get from these others or i get someone who just sits on the other end of the phone and says "ummm yea ummm yea, if you want to, ummm yea we have done that before"
wtf:wtf:
