Can someone get me a wiring schematic
Can some one get me a wiring schematic for a Ign switch for a 1999 F150 XLT. I am having trouble determining what wires belong to Ign. and what is Acc. Yes I have test and come up with 4 Ign. and 2 Acc. but everyone keeps telling me this is wrong. I have 8 heavy gauge wires in my Ign. switch and would like to know what is what.

Not sure where you got this, as the key position can be hot in accy, hot in run, hot in run / accy, hot in start positions
From the 2001 EVTM ( don't have the '99 evtm 13-7 handy, so use at your own risk ). BJB ( aka battery junction box, engine compartment fuse panel ) Fuse #113 ( hot at all times ) is a yellow wire to B3 & B1 on the switch, BJB fuse #111 ( hot at all times ) is a Light Green w/ Violet stripe wire to B5 & B4 The output of the switch Red w/ Black strip wire = Hot in run. Black w/ Light Green stripe wire = Hot in run & Accy positions Dark Blue w/ Light green stripe wire = Hot in run & Accy positions Red w/ Light Blue stripe = Hot in start Gray w/ Yellow stripe = Hot in Run position This makes 4 wires into the switch and 5 out of the switch from the 2001 EVTM cell 13-7. |
So if I am following you right:
Yellow and Light Grn/Violet are 12 + Constant Red/Black and Gray/Yellow are Ign Black /Light Grn and Dark Blue/Light Green are Acc Red/Light Blue is the Starter wire Most of the wires match up to my Ign. May have missed the Red/Light Blue so will have to look at it again. |
I hope you didnt miss the red/light blue, because thats your starter wire that you told me you had hooked up. Here is the list again...
Viper Color - Truck Color Pink - Red/Black Red/White - Light Green/Purple Orange - Black/Green Violet - Red/Light Blue (Car Side) Green - Red/Light Blue (Key Side) Red - Light Green/Purple Pink/White - Gray/Yellow Pink/Black - Shouldn't Need this One Red/Black - Light Green/Purple |
Sorry that didn't click into my head, No all here tonight LOL. I have everything hooked up the way you have it minus the Acc. and the Power wires. Was just looking for clarification on what the wires exactly are. Everything works fine when I put the key to the run position but when I take it out it just cranks and the only light that lights up is the ABS light. So I am thinking that there was possibly a another IGN wire that needs to be hooked up. I will be re-looking at it again tonight.
As for the Light green/Violet, I do not show 12+ in the off position only the Yellow wires show 12+ Should I use the Light Green/Violet instead? Alarm works so its getting 12+ constant. |
Got it working, had to hook the Blue/Grn wire to Ign 2 and the Black/Grn to Acc. Now just have to figure out how to program the Bypass. Does anyone know what Ign. wire controls the HVAC?

EATC or Manual system ?

There are 2 fuses that are hot in run position, Both CJB ( aka Central Junction Box / cab fuse panel ) fuse #24 and fuse #5.
Fuse #24 -> White w/ Violet stripe wire Powers the function selector switch Fuse #5 -> Light Blue w/ Pink stripe wire powers the blend door motor. Fuse #24 is fed by the Gray w/ Yellow stripe wire from the ign switch. Fuse #5 is fed by the red w/ Black stripe wire from the ign switch. Blower motor is hot at all times via BJB fuse #5 to the blower motor relay and then to the blower motor after the relay. |
Thanks for the help SScully. I'm going to throw in a relay and hook that one up as well. This defiantly helps out. Kinda sucks not having the heater when on when the truck is running on remote start.
