External Fuel Pump Relay Wiring.
Hey guys, I need some help wiring up an external fuel pump relay and can't seem to get it right. I've searched and found some information on the vortech relay, but it seems that information could be wrong.
Motor: 2004 DE
According to the FSM, ECU pin 113 controls the on/off for the current relay. I would like to have it operate the same way. Is this a way for me to maintain that? I know I can easily wire it to a manual switch, but I want the ECU to do the switching.
What I have so far. Does this look correct to anyone?
SPDT Relay pins:
30 - From ECU pin 113
87a - [Not Used]
87 - To Fuel Pump
86 - IGN +
85 - Ground
Stock Setup: (sorry for the lame diagram)
12V From "On" or "Start"---|~coil ~|--To ECU Pin 113
15A Fused from IGN Relay--|*____*|--To Fuel Pump Pin 1
Any help is greatly appreciated. Thanks in Advance.
