I'm new on here, and I have a Mk2 Cavalier LX which I'm converting from a 1.6carb to a 2.0SRI 130 - Again from a Mk2.
I've got the engine in ok, and the ecu is fine. The engine's not running yet as I have a problem with the wiring loom cos I think a small part of it is missing.
About 2-3 inches from the positive battery terminal, I have a plastic connector block which comes out of the new loom. I have nothing to connect to this as yet. The old Mk2 1.6 coil had a small black module mounted underneath it, but for the new engine all I got was a cylinder type coil.
There are 7 wires on this connector, which I've labelled below with what I think are there uses;
A - BLANK
B - BROWN, WITH BLUE STRIPE, To dash for ECU light
C - BLUE, WITH RED STRIPE, Leave disconnected (speed MPH)
D - BLACK, Ignition to black on old coil wire
E - GREEN - Rev counter, to green on old coil wire
F - BROWN, WITH YELLOW STRIPE - leave disconnected (fuel comp
G - BROWN, WITH RED STRIPE - don't know
H - BLACK / WHITE - fuel pump via 20A fuse.
In order to wire this up properly, should I have a small black module with the new coil???
The wires I have coming from the old loom (which used to connect to the old coil) are GREEN, BLACK and BROWN. The green went to the '-' on the coil and the black to the '+'. then all three of the wires went to the small black module which has one cable coming out to a small platic plug which attached to the side of the old distributor.
I'm stuck mainly, as to how I should wire up the coil. I could do with looking at somebody's Mk2 SRI 130 (Any offers??????).
I've looked at Mk3 Cavs, but the wiring loom is different.
from memory there is a small black module under the coil measuring about 2" by 3" and about 10mm high has a black plug going on to it that has something to do with the spark i know there the same on all mk2 1.8 and 2.0 8v astras and mk2 cavs it could be that
the coil in a cav sits near to the battery
i have one in the garage if you need a pic email me and let me know
