doing a 5.0 swap to a 78 f100

[nicksz24cavy]

heres what ive got going, I have an unwrecked 1997 5.0 explorer that's the donor, beside it is a 1978 f100 swb that needs that 5.0, I want to keep it fuel injected, and keep coil packs, can someone please help me figure out what ive got to do wiring wise to get this beast fired off in the 78 f100, ive got a diagram of the c115 harness, but I don't understand what goes where, please help me, thanks

Ford 5.0L 302ci engine swap electrical information

I installed a '00 302 in an '82 Volvo and I suspect that the body wiring of the '78 is going to be very similar. Your '97 is easier because you do not have PATS to deal with.

Here are the C115 connections I had to satisfy.

1.) Pin 1 (red/light green) (circuit 16, page 13-16) Ignition coils power
2.) Pin 2 (tan/yellow) (circuit 11, page 62-2) Tachometer
3.) Pin 3 (pink/light blue) (circuit 915, page 25-6) Data port
4.) Pin 4 (red/light green) (circuit 810, pages 30-2, 59-6) Brake torque converter unlock
5.) Pin 5 (dark green/yellow) (circuit 238, page 25-1) Fuel pump on signal
6.) Pin 6 (pink/light green) (circuit 658, page 23-2) Dash MIL/CEL
7.) Pin 8 (yellow) (circuit 37, page 25-1) PCM permanent B+
8.) Pin 9 (red) (circuit 361, page 25-2) Fuel injector/IAC/MASF B+
9.) Pin 11 (tan/orange) (circuit 914, page 25-6) Data Port
10.) Pin 12 (tan/white) (circuit 234, page 30-2) Transmission Control Switch (OD Lock out)
11.) Pin 15 (light blue/orange) (circuit 926, page 25-1) Fuel pump relay
12.) Pin 16 (red/white) (circuit 39, page 62-2) Coolant Temperature Sensor
13.) Pin 22 (violet) (circuit 107, page 14-1, 25-6) PCM reprogramming power from Data Port
14.) Pin 26 (dark green/white) (circuit 253, page 62-2) engine oil sensor
15.) Pin 34 (black/white) (circuit 570, page 10-2) Ground
16.) Pin 36 (light blue/orange) (circuit 34, page 13-5, 25-6) O2 sensor/transmission power
17.) Pin 40 (white/light green) (circuit 911, page 62-6) 'OD OFF' indicator light
18.) Pin 41 (light green/red) (circuit 904, page 12-1) ALT light
19.) Pin 42 (yellow/white) (circuit 36 page 12-1) Alternator power

The circuit and page references are to the Ford Electrical Schematic book which I would suggest would be a handy reference. They are usually available on eBay for $20 or so but all the pages you need can be found here:

Getting all that to work will require the addition of at least 3 relays, Start, Fuel Pump and Torque Converter unlock. You are also going to have to add a high pressure fuel pump. For a long discussion, too long a discussion, on the subject see here.

the Truck (78) does not have any of that, i really just want to get it fired up, I'll do the sensors and stuff later after a get it started,

OK, here is the minimum needed to start the car.

1.) Pin 1 (red/light green) (circuit 16, page 13-16) Ignition coils power
2.)
3.)
4.)
5.) Pin 5 (dark green/yellow) (circuit 238, page 25-1) Fuel pump on signal
6.)
7.) Pin 8 (yellow) (circuit 37, page 25-1) PCM permanent B+
8.) Pin 9 (red) (circuit 361, page 25-2) Fuel injector/IAC/MASF B+
9.)
10.)
11.) Pin 15 (light blue/orange) (circuit 926, page 25-1) Fuel pump relay
12.)
13.)
14.)
15.) Pin 34 (black/white) (circuit 570, page 10-2) Ground
16.)
17.)
18.)
19.)

Plus a lead from the ignition start key position to a relay to feed a higher current to the starter solenoid that doesn't go through C115.
