2001-2003 F-150 Remote Start w/Keyless Pictorial

Looks like the last link didn't work so here it is. Thanks!

OK. To power the extra ignition wires you will need two 30/40 Amp SPDT relays and the 5 pin harness plus an in-line fuse

holder with 20 Amp fuses and a couple of 1N4007 diodes.  Wire as follows :

Relay 1 for IGN2 :

Relay Pin 85 to R/S IGN (-) Output Blue wireRelay pins 86 and 87 to +12V constant through 20 Amp fuseRelay Pin 30 to F150 RED / Black wire in ignition harness

Relay 2 for ACC2 :

Relay Pin 85 to R/S ACC (-) Output Brown wireRelay pins 86 and 87 to +12V constant through 20 Amp fuseRelay Pin 30 to F150 BLACK/ Light Green wire in ignition harness

Connect the diodes across each relay, pins 86 and 85, with the diodes band towards pin 86.

There are ample +12V constant wires at the main ignition plug to individually power each circuit.

Soldering is fun!

Thanks again for your help. Do I have to add those relays in because there aren't enough outputs on this unit or was there another reason? Just asking out of curiosity as I'm new to all this. Thanks

Oh, I see I should have read more carefully, thats to power the - outputs from the red 3 pin plug, I see what you're saying now. Thank you

Yes.  The truck has many ignition wires that need to be powered during a remote start.  The R/S unit has the capability to power some of them but not all.  These vehicle circuits are designed / engineered to be separate circuits so they can't be tied together and powered by one R/S output.  The R/S does have low current (-) ignition outputs that can be used to energize relays that in turn can supply high current (+) outputs for these vehicle circuits.  Extra work but necessary to properly remote start the engine.Soldering is fun!

I gotcha, that poses another question then, the R/S has a programmable 4th relay that I can set from acc +/- ign +/- or start +/- could I use that for one of them and just add one additional relay from one of the low current outputs to the ignition wiring?

Didn't see that on the diagram but yes, if it is a high current selectable ignition type output, use the 4th relay ( flex output ) in lieu of an external relay.Soldering is fun!

Thanks Kreg, I appreciate all your help, I'll try to wrap it up in the next few days and I'll let you know how it went.

So here's an odd update, this morning when I was waiting for the truck to warm up I set the R/S into tach learning mode, it went through its sequence to confirm that it did learn and then when I got to work this morning and shut the truck off it kept running. In the end I had to unplug the 9 pin main harness at the R/S to get the truck to shut off so now I'm going to have to figure out whats going on there.

Is your brake safety interrupt wire connected? The remote start system should have "shut down" after you put the key in the truck and pressed the brake pedal to shift into gear. Ricky
