I've searched for some answers on converting 84 G bodys from T1 to T2.From the way I see it from looking at wiring diagrams you need to literally rewire the entire car front to rear!I have an 88 t2 Daytona shelbyz that has all the options my 84 has except rear wiper.I Have removed the dash and ALL the wiring (doors windows seats etc).going to finish when the weather gets a little better.Will be removing every wire in the donor car.This looks like a lot of wiring work just to make my DD 84 a little faster.I would hate to disassemble my perfectly good running 84 then end up not being able to get it back together.Will some one that knows for SURE, is this all necessary?Seems to me I could get by just changing injector sizes in the two lean cylinders.Any help and suggestions would be GREATLY appreciated!Serious answers from people with experience only please.I see several 84 owners who think you can just change to 85 engine harness and use an overlay--I don't think so. HELP PLEASE!
