On older engine versions (electronic module with 1+ 4 pin plug):
See Figs. 74-24 and 74-26.
Insert O-rings (33) 34x2 in the groove (34) of the cylinder heads and remove the
plugs from the intake openings. Fit both intake manifolds (35) with pre-
assembled ignition electric set and tighten crosswise with 4 allen screws M6x25/
70 and lock washers. Insert rubber buffer (18) into bracket (36) of ignition
housing and tighten with hex. nut and lock washer.
Place distance sleeve (37) in position and fix ignition electric set on crankcase
with hex. screw (38) M8, washer and lock washer. Now tighten all screws and
nuts of the ignition electric set.
Fit grounding cables (9), (10) and (26) on the nubs (41) at the intake manifold
with hex. screw (8) M6x16 and lock washer. Attach both 4-pin plug connections
(electronic module to trigger coil kit) and secure with tie wrap.
â—† NOTE: The pick-up cable of ignition circuit A (top module) is marked at
the end of the isolating hose with the colors blue and red. Those
of ignition circuit B (bottom module) are green and colorless
(neutral) respectively.
â– CAUTION : The cable shielding must be fully inserted into the cable clamp
to assure optimum grounding.
Connect the two red cables coming from the charging coils with the two pink
cables of the SMD electronic modules. Route the whole cable assembly into the
cable clamp and attach it to the ignition coil holder (17) together with the
electronic module using allen screw (6) M5x25.
Fit two each ignition cables (39) for the lower spark plugs into the glass fiber/
silicone tube (5) and route them between cylinder heads. Screw resistance
spark plug connector (40) onto the ignition cables, secure with tie wraps (25) and
fit onto the spark plugs as shown on the wiring diagram.
Attach 4 ignition cables each for cylinders 1 - 3 and 2 - 4 to the new coolant hose
