Re: carb 355 swap

i believe that 2 into 1 wire goes to your starter...if you could get pictures of the wires that would be more helpful

Re: carb 355 swap

that orange and red gives power to your car so that will go on the big starter bolt along with your red wire from your battery

there will be a plug somewhere in your harness that will plug into the alt that plug will also have a short red wire coming off of it with an eyelet ont the end that shrt wire will go on the back of the alt. as well as the thin wire coming from the positive battery wire

chances are if you unplugged the ecm the fuel pump wire was on that side..not 100% sure but pretty sure that what happened you need to put a manual fuel pick up in the tank and a mechanical fuel pump on the block now that your running a carb

With the ECM gone what mods have you done to suit the carb install?
You have nothing to run the pump anymore and you can't use EFI fuel pressure to the carb if it did
What are you doing about the convertor lockup now the ECM is gone?

Re: carb 355 swap

for the lock up i put the tci lock up in the 700 and for the fuel pressure i bought a fuel pressure regulator thatll knock down the pressure to 6.5lbs for the carb so i can keep the fuel pump

But what did you do to supply power to the pump since the pump relay operated by the no longer there ECM will no longer work?
