The 1985 - 1987 Power Module (TBI)

[ 10 Way Connector | 12 Way Connector ]

Description

This page contains information specific to the 1985 through 1987 power modules used on all 2.2L and 2.5L throttle body fuel injected engines. If you are not familiar with what the power module is, please see the Understanding The Chrysler Engine Control Unit page before reading this one.

Connectors

The power module has two connectors with large pins (a 10-way and a 12-way). The following sections contain a diagram and pin-out for each. The wire colors are in the color/tracer* format (BK/WT* = black wire with a white tracer). Below is a list of color abbreviations:

Code	Color	Code	Color	Code	Color
BK	Black	LB	Light Blue	TN	Tan
BR	Brown	LG	Light Green	VT	Violet
DB	Dark Blue	OR	Orange	WT	White
DG	Dark Green	PK	Pink	YL	Yellow
GY	Grey	RD	Red	*	tracer

2	J2	14	DB	12V power feed from ignition switch "run" and "start".
3	K14	18	DB/WT*	12V power feed to logic module (from J2)
4	J1	12	PK	Direct battery feed
5	K18	18	TN	Fuel Injector driver output
6	Z1	14	DG/BK*	ASD relay power output
7	K17	18	WT	Fuel Injector driver output
