Old but Newb

Hey, from Maryland, Planning a 93 Caprice wagon TBI swap into my 72 2wd blazer. K5 Blazer was a North Carolina truck I bought almost 20 yrs ago. Finally had time to remake it into a 2wd truck using mostly original GM designed 5 lug axles and cross member with trailing arms. Currently a 350 with a 3 speed manual Saginaw. Drives decent, strait down the road but its not the everyday driver I was hoping for, The Caprice wagon with 350 TBI , I have owned for 17 yrs and has been a great reliable car. I hope to get some help with the wiring here, I am marking all wiring and connectors as I go hope to make it as quick and painless as possible. Also hope to pull the engine and trans together, maybe simplify the swap. We'll see.......Cheers.....Ed.
