EEC IV code help
I have a 91 5.0, 5 speed. I am getting codes 51, 22. 23. 54. 34. 67. and 82.
Which represent ECT, MAP, TP, ACT, EGR, NSS, and TAB. I have tested the ECT and ACT and the problem that the book I am using, How to tune and modify ford fuel injection, says is wrong is the signal return wire. The book lists it as a black and white wire that connects to the ECU on pin 46. My wire is grey and red and tests good with a continuity tester. This started when my car fried its computer and I replaced with a refurbished ford A9L. Any suggestions would be appreciated.

70mm BBK throttle body

Mac shorty headers
Mac Cold Air
Flex-a-Lite electric fan
Stock injectorsBBK adjustable fuel pressure regulator
