I know this has been bounced around in various other posts. I just want to make sure as possible next step.
Vintage air installation is complete. Found a switched wire under the dash that is only powered in the run position, no power on crank and working fine for VA.
Now onto Sniper EFI. Everything is installed. My biggest concern in the installation was finding a switched wire that would be powered in the run and crank key positions. PO had a Carter carb which I switched to Edelbrock with electric choke. Choke worked fine so never explored the power source. My hope was that this would be the wire to hook up to for the sniper pink wire switched power source for the ECU. My concern was that this would not be the case.
Fired up the sniper and everything great until crank, and then screen goes blank and resets once key moved back to run. I understand an extremely common problem among this install.
Wife and kids are away on summer trip so no easily accessible help for testing power and Murphys law holds true.
Now I need to find a switched wire for both run and crank.
Pulled my ignition switch. Found out elec choke wire going to center stud of pigtail. No good. Two purple wires together. Green with black, green with red and red with green wires on another location. Put the switch back in before I realized I should have taken pictures. Pictures would be hard to get as this is original wire harness and nothing moves. In reality a huge f'ing mess of wiring behind the dash from multiple POs.
How to wire into ignition switch to get a switched wire for both run and crank for the sniper?
My plan was to move to painless harness this winter with new switches and gauges but after seeing the disaster behind the dash it may be time to move on with this sooner rather than later.
