Narrow A$$ Racing
i have i speed pro system bank to bank that is dos for a 4.6 cobra
have a question
the wire is a ground trigger out of the speed pro?

i am using it to trigger a 30a relay when i ground the wire the fan comes on and when i coonnect the wire to the speed pro it never comes on

the system settings are on=161 off=156

the fuel pump wire is working is there another setting that i am missing is there a way to test the wire for the speed pro to see if it is good or not

thanks for the help
What is the serial number of your ECU? There is a known problem with some of the 4.6L systems relating to fan control, and if this is the case I'll be happy to take care of it for you. I'll need the box though... please reply when you have a chance and I'll do what I can to help.
