Engine Harness Connections
Connector C100
H - Coolant Fan relay control (2 & 3)
J - Coolant Fan Relay Control (1)
Are these ground activated? What does the 1,2,3 designation mean?
Connector C105
B - Power Feed from Injector Fuse #10
I couldn't find an Injector Fuse #10, only Engine Fuse #10 in my Haynes manual. Is this a typo, if not what A rating does it need?
Connector C210
B - Ground feed to fuel pump relay
D - Feed from fuel pump and fuel pump relay to prime connector
I'm guessing that B is the important one. It ground activates my relays in the back of the car per the PCM, same way my BS3 was. What is D for and do I need it for the pump to work properly. Currently I have a dual Walbro setup in the tank with two relays. Primary is ground activated and the other 12V activated.
Connector C220
G - VSS
J - Fuel Pump Relay Control
K - Coolant Temp Feed
Can the VSS and Coolant Temp signal be used for aftermarket gauges? What is the factory voltage range for those sensors? Is J the fuel pump relay control I need and not the previous one on C210? Is C210 the ground and C220 the 12V switched source?
Connector C230
D - Tach signal
E - Theft Deterrent Fuel enable
Can the tach signal be used, same question as above. Does E need to have power applied to it so the PCM will continue to provide signal to the pump eventhough I disabled VATS?
