yeah I don't have any relays on the car just fuse box stuff but you're correct now that you brought that up. I put that shifter on today and I'll be damned if you're not right that wire seem very thin. I know the nitrous solenoid drives a little over 16 amps but the fuel solenoid seem to be way less. Like just a few amps if that. I'll go ahead and get a relay and put that in there... Thank you for the wise suggestion...
