The ECU and MAP unit are already fitted.

Connect the green 3-pin plug on the

engine loom to the connection on the

MAP unit. Connect the short pipe on the

MAP unit to the corresponding connection

on the throttle body using the rubber

vacuum hose provided (125 only).

Connect the black wire from the vehicle

loom to pin 16 in the ECU plug (140 only)

The ECU for the Academy is already fitted

under the battery. The MAP unit is

positioned on the passenger footbox.

Connect the oil pressure switch from the

LH side of the engine block to the

connector from the main loom which can

be found clipped to the outside of the

passenger foot box.

The two, paired, black/yellow wires with

ring terminals in the engine loom are earth

connections. Attach both pairs to a

suitable earth point on the bulkhead.

The green, green/purple pair (with

grommet) in the engine loom is for the

brake light switch. The brake light switch

is inside the drivers pedal box and the

harness may be connected during

installation of the steering column. Pass

the brake light switch harness through the

hole in the rear of the pedal box, refer to

Fig 44 and push the two female

connectors onto the male connectors of

the brake light switch (orientation is not

important). Fit the grommet into the hole

and ensure that the harness will not foul

the steering column or pedals.
