Alright I need some help...94 5.0 engine wiring
Engine Wiring Diagram
Fig. 28...Over at the Constant Control Relay Module, how does the PCM power relay get hooked up??... The PO really butchered up the wiring and I'm trying to make it run for a little bit, before next summer when its new harness time..

The colors are: Red 24 which goes the fuel pump monitor and injectors and stuff, Yellow 10 which is fused and is the power for the computer, Red/Lt Green 13 which is also fused and goes to igniton module and coil, and Blk/Wht 15 which is ground..

I need to know which color goes to what on the relay..87, 30, 86, 85

I saw on FordFuelInjection that
86 - control current in
85 - control current out
30 - power current in
87 - power current out

Sorry if this is hard to follow, and I appreciate any help I can get..
I'm assuming yellow is 30, 87 is red, 86 is red/lt green and 85 is the ground??
But I don't want to ASSouttaUandME..
