I have a 2004 IC FE with a DT 466 .The warning system that lets you know if anything went hay wire with engine systems . We had a driver over heat and engine because of no audible warning . Wait to start heater isn't working either . I suspect a relay . but a wiring diagram fuses what could be wrong if it's not a wiring issue . If you have a simple diagram I will accept that too . Thanks

My understanding is the ECM turns on those relays . I see the intake heaters coming off the starter . I am wondering where the power comes from for the power side of the relays . Make sense ?

Hey Doug,
The guys up in Yelm had/have some of these IC-FE's and may be able to help.
