if i suppiled the two wiring harness one from tpi and one from lt1 could come one make me a harness i dont feel comfortable about cutting wires i be willing to pay $$$$$ i would need all the smog equiment wiring there

 

sure, anything is possiable. might help if you said what you're doing and what you have. if you're doing a lt1 swap into a thirdgen you'd need the lt1 ecm too, eliminating the need to hack up 2 harnesses to make one.

 

i have a 1988 iroc with tpi and i do have the ecm

 

As long as you know what wire does what via diagram or something, electrical work is easy. Just take your time and use the right tools. Solder as much as possible. Use wirenuts. Things like that. Just don't twist crap together and use electrical tape.
