HELP.....Wire ID

I have an 89 F150 XLT Lariat, EFI Inline 6 300ci.
I need help Identifiying a few wires in the injector harness off of the main wire harness.
These are inside one connector:
Injector bank 1 (TAN/RED)
Injector bank 2 (TAN/ORG)
Coolant temp (LT GRN/YEL)
Air charge temp (YEL/RED)
VPWR(RED)
SIG RTN(BLK/WHT)
The 2 in the connector that I don't know.
RED/WHT?????
BLK/LT BLU?????

Outside that connector:
TAN

I read schematics very well and am not able to find these wires on the drawings. The shematics I am using are from

HAYNES REPAIR MANUAL
Ford Pickups and Broncos
1980 - 1996 2WD and 4WD

Help would be greatly appreciated.

Red/white is the temp sending unit wire that feeds the temp gauge in the dash.

I am not sure what the black/lightblue goes to.

How about the TAN wire. It's outside the 8 pin connector. I noticed that it had been severed. It is in the same sheath with the 8 pin connector. Hell...... it might not even be TAN as nasty as the wire is. but I traced it all the way back to the firewall. It lives in the Brown 8 pin connector that connects on the drivers side of the engine bay right along with the black,gray and white 8 pin connector.

I know that the wires don't come from the ECU.

We need the full fledged version factory schematics to find these wires. The Haynes manual just hits the highlights, and it's a function schematic, were the wires are grouped according to the circuit they serve. The factory diagrams have this, but they also have harness diagrams and connector pinouts according to the wire and connector location. I don't have the factory schematics for your truck.

Thanks for your help. You helped me solve one of the mystery wires. Maybe someone else will come along that might know or that could go out to their truck like mine and see. I am going to go to the salvage yard and see if I can find an engine and harness intact. That is looking like my best bet.

The BLK/LT BLU wire has been identified as going to the Injector Blower by another knowledgeable individual in another F150 Forum. The only one hanging around now is this TAN wire. Again it is next to the Fuel injector harness in the same sheath. It was severed when it was discovered so I have no idea how long it has been this way or what it was connected to. If any of you guys have an 89 EFI F150 XLT I6 300 it would be greatly appreciated if you can run out to your truck and take a look.
