Working an a 88 F150 w/ 4.9L, Mazda 5 spd Manual O/D trans & OEM FoMoCo Cruise

I need a wiring schematic/ diagram so I can figure which wires to cut and splice to eliminate the "idiot trigger" all together & still have my cruise work.

Clutch safety switch allows start only when clutch is depressed, & shunts, or disconnects Cruise Control when clutch or brake are touched. Switch has 5 wires. Mine has ZERO adjustment left. Now the cab floor is getting in the way of starting the stupid truck.

The clutch safety switch is as stupid as the dual tank, fuel pump, and fuel gauge sender switch is. It looks like FoMoCo sub contracted GM to wire up their lat 80s Trux. . . .

Sure glad my Slick 60's F 100 is nothing like this F 150!
Any help or suggestions will be greatly Appreciated I Promise!

Have you checked the fluid in your clutch master cylinder? The slave cylnder leaking is a common problem in these things. If you go to add fluid to the clutch master cylinder don't forget to remove the rubber cup under the lid. Just a suggestion.

 

FWIW,
I replaced the Clutch M-Cyl several months ago and it has been working fine. Friction point is abt 1/3 up off floor, what's changing is where start circuit engages & there is no adjustment to that.

If I didn't have cruise I'd just have spliced that stupid switch out of the circuit. I'm just not sure which of 5 wires are what.

It looks as if nobody else is sure either so I'll climb under my dash with a VOM & finger it out myself.

Thanx Anyway, know where I can get a good 5.0L Roller Engine complete with an AOD? I've had it with this 300 I-6 finally, really.
