| 1986 TI Logic Module Wiring Diagram (and '87 L-body TI) |
| This page contains information specific to the 1986 Turbo I Logic Modules. In the 1987 L-body platform did not recieve the same electronics updates that the other platforms received. Therefore, this pages also applies to the 1098 TI l-body vehicles. These logic modules have the MAP sensor built into the logic module case and is connected internally. Supposedly starting in mid-1986, some Turbo I logic moduels were equipped with the electronics necessary to control the Turbo II 4-wire AIS MOTOR. There is no way to identify them from the outside if a particular logic module has this capability. The only way to tell is to open it and look for the eleectronics. CONNECTORS The Logic Module has two 25 pin conectors. The following sections contain a diagrama nd a pin-out for each. The wire colors are in hte color/tracer format(BK/WT = Black wire w/ white tracer/strip.) Below is a list of color abbreviations: |
| Code BK BR DB DG GY |
| COLOR Black Brown Dark Blue Dark Green Grey |
| Code LB LG OR PK RD |
| COLOR Light Blue Light Green Orange Pink Red |
