|Making the connection|
Once the insulation is stripped back, twist the tapping wire around the bare wire, Solder it, being careful not to leave any sharp points sticking out that could pierce the tape and short to another wire.
|Tape up the connection |
Tape up the connection with 2-3 wraps of tape. All taps will be made this way.
|STST (Strip, Twist, Solder, Tape)|
The four splice connections will be made by stripping about 3/16" of the insulation from the two wires, twisting one over the other, then soldering and taping. For the rest of the instructions, the tap or splice connections will be referred to as: STST (Strip, Twist, Solder, Tape)
|Rear harness |
|Rear Car Connectors|
The connectors of the MCM and BCM each have a unique shape that will help you to identify the correct pin# for each of the connections. Since the harness is open, you first find the pin, then follow the wire out of the rear of the connector, and confirm that it matches the color indicated for that pin.
Next, we need to make a series of connections from the wiring harness to your car. There are 15 connections to make,in the rear and the protocol is listed below. It will start with the color of the wire, details about it, and where it needs to go in your car.
Warning: There are two brown wires. The loose one is for power, the other is part of the ribbon cable. If you connect these backwards, smoke will come out, and the car will never be the same again.
|Brown Pin 1 to black/yellow with silver dots Switched 13.6V MCM A-9 (tap)|
|Blue Pin 6 to Black/Yellow MAMODE 2 MCM A-3 (tap)|
The Blue wire in the ribbon end taps into the Black with yellow stripe coming from MCM A-3, STST the connection. This is the MIMA signal that controls the availability of assist or charging.
|White with orange stripe to Brown/Yellow with silver dots wire Logic ground MCM B-9 (tap)|
This important connection taps into the Logic ground used as a reference by the MIMA board, and the MCM and ECM for the main MIMA signals. STST the connection.
