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
