This 80amp relay activates the fuel solenoid on years 94-98.5 12valve. If this relay is bad. your engine will crank fine but will not start because the fuel is not getting to the engine.
THE ORIGINAL RELAY IS A DUAL RELAY THAT IS MOUNTED ON THE FIREWALL.
THIS 4 PRONG PLUG ON THAT RELAY WILL PLUG DIRECTLY INTO THIS RELAY AND WORKS FINE.
