Fan Relay and Fuel Pump Relay, doc, whats this wire? :) Options

[jcbass7]

After searching i have not quite yeilded the answers i need..

My swap is done, but my fans are wired to run all the time.
what can i do to make them come on and off at a certain temp?

should i buy a kit like this:
Two's R Us Fan Relay and Thermo

or can i figure it out without dishing out the cash?




Fuel pump relay... do i need to do anything with this? I think its on all the time, should it not be? etc. i don't want to burn the pump out.. its an SW20 pump and i usually run around 45-48psi on average when driving.

Are you sure the wire isnt a light green with a black stripe?

I remember when I wired up my swap I left that LG-B wire coming out of EA1 taped off. You dont need it hooked to the ecm. My cooling fans work just fine. I wonder if your thermostat is open or if yor water temp switch isnt working correctly. Maybe its just too cold for the fans to kick on.
Dr. Tweak: Correct me if Im wrong, but dont the cooling fans kick on when 12v is applied to the LG-B wire because it turnes on the fan relay no.2, then fan relay no.3, then applies power to the fan motor which is already grounded? If Im looking at this right. Later
