Fitting Wiring Harnesses
Note
The F2 and F1 designations in Figure 4 refer to the relay location stamped on the bottom of the fuse box cover located under the hood.
1. Connections in the relay/fuse box:
M1994-95: remove relay holder position F (fog light; will be replaced by two micro relay holders 44 09 934).
Pos F1 = fog light relay
Pos F2 = Vacuum pump relay
Note
The fog light relay will either be a standard size relay (approximately 1x1x1 in.) or a half-size relay. For a standard size relay, follow the instructions in step 2. For a half-size relay, skip to the instructions in step 3. For these cars, some of the wiring components supplied in the kits will not be used.
2. Connections for replacing the standard size fog light relay; use adaptor harness (47 39 694) with relay holder (44 09 934).
a. When fitting wires as indicated in the following steps, be sure to route all of the wires on the bottom side of the relay panel. This will allow you to just raise the micro fog light relay socket into place when this work is completed.
b. Remove the Brown/Black 1.5 wire from position 1. Refit this wire in the new micro relay holder position 1.
c. Remove the two Red/Black 1.0 wires from position 2. Refit these wires into position 2 (micro relay holder).
d. Remove the Brown/Black 0.5 wire from position 4. Refit this wire in contact housing (91 24 157) position 2.
e. Remove the Yellow/Red 0.5 wire from position 5. Refit this wire in contact housing (91 24 157) position 1.
f. Connect the micro relay holder "fog light" with the contact housing (91 24 157).
g. Fit the pre-wired relay holder (44 09 934) into position F1 and make sure that it is properly secured.
3. Connections for the half-size vacuum pump relay and fuse; use adaptor harness 47 39 686. A micro relay is factory-fitted in position F1.
a. Fit the micro relay socket into position F2. Make sure it is properly secured.
b. Fit the Yellow/Red 1.0 wire to fuse no. 4 (fused side).
c. Remove the Red 1.5 wire from fuse no. 2 (fog light) position 1 (unfused side).
d. Refit this wire in contact housing (91 24 157) position 2.
e. Connect the Red 1.5 wire from the split contact (41 17 560, stamped on the connector) to fuse no. 2 position 1 (unfused side).
f. Remove the Brown 0.75 wire from fuse no. 10 (headlight wiper) on the unfused side.
g. Refit the Brown 0.75 wire that came from fuse no. 10 in contact housing (91 24 157) position 1.
h. Connect the split contact (41 70 560) Brown 0.75 wire to fuse 10 on the unfused side.
i. Fit the Brown 0.5 wire (from the split contact) into the micro relay bracket (vacuum pump relay position 3).
j. Connect the Red 1.0 wire (from the split-contact) to fuse no. 4 position 1 (unfused side).
k. Plug the split contact (41 17 560) into the contact housing (91 24 157).
CAUTION
Reversing the connections for the vacuum pump harness will blow fuse # 4 and the pump will not operate. Make sure to install the black connector (item 1, Figure 5) to the vacuum switch and the white connector to the pump (item 2, Figure 5).
1. Route the vacuum pump harness through the fuse box outlet and fix with cable ties to the main harness on both sides of the outlet seal. Refit the relay/fuse bracket in the fuse box.
2. Route the vacuum switch wires (black connector) with the OE harness along on the fire wall to the switch location. Use three cable ties (79 71 864) to secure the harness in place.
3. Route the vacuum pump wires (white connector) beneath the expansion tank, forward along the OE front harness to the left front turn signal location, and further to the pump bracket location inside the left fender. Secure with three cable ties (79 71 864).
4. Refit the relay/fuse box and the expansion tank. Install three cable ties (85 52 633) to the front harness.
5. Fit the two micro relays (42 24 192):
a. M94 - 95: positions F1 and F2 (see Figure 5).
b. M95 1/2-: position F2; position F1, fog lamps, is already in place.
6. Attach the ground wire to same ground point as the battery negative cable on the inner fender near the maxi fuse box.
