Hey pal, I purchased the 91008589 tpi harness and got it all installed but the eng quits as soon as I let go of the key and it did the same thing when I started it on the motor stand with a starter button so its not the ing switch. And I got everything hooked up right but unless there is something with the harness I might've missed, I even wore the paper tags off the wire ends fooling with it Ive tried to contact fuelinjectionconnection tech dept and didn't get a call back, im tired and aggravated can ya help me? thank james

Does this harness remove the need for the coded ignition key that these Corvettes and the 1227165 ECM required? I have the ignition key that goes with the ECM but hopefully I will not need it. Thank you.
