The green wire from the distributor should got to the -ve (you
mentioned +ve) terminal on the coil, if the car has a rev counter
another green will leave the coil, possibly go through a suppressor and
go to the rev counter.
The black wire on the distributor should go to the +ve on the coil and
then via the removed resistive lead to an ignition switched feed in the
main loom.
The brown on the distributor is connected to ground, preferably the
battery earth not the engine.
The relay with the 2 diode attached is almost certainly the one for the
headlight flap motor.
The diodes take signals from the main beam and dipped beam or sidelights
(depends how it was wired) and operate the relay for the flap motor if
either are on.
The diodes are needed so that the relay is active if either of the 2
circuits are active.
The flap relay is a changeover so it always supplys power to one of 2
terminals on the flap motor.
The other relay may be for front fog or spot lights if you have them.

cheers Jim
ive checked that wire (not green though on account of the wiring being
a bit of a mess) and it does indeed go to the pos on the coil, so
that's one wire sorted for the CVH 3 pin wiring, ill just wire in the
neg and earth separate and bypass the resistor
while on the subject of electrics ive one more query
when I was stripping the engine bay down to prepare for engine removal
I came across 2 relays and a sort of scary looking plastic bit with
diodes or something lurking out from one of them
unfortunately I cant find a reference in the Haynes manual for a
"badly bodged pair of relays with spade connectors instead of a proper
relay mount" section,
they were just loose dangling rather close to the alternator drive
belt (nice) so my next questions are
what are they?
do I need them now ive swapped to CVH?
first picture is the 2 relays together and they were bundled together
with a bit of tape, weather that meant they work together or not im
not too sure

the next pictures are of the scary wiry bit attached to one of the
relays

other than the horn I have no other relays under the bonnet and if I
need them id like to tidy them up, replacing them with new ones fitted
to proper relay holders wont be too much of an issue (as I did with
the horn) but im puzzled by the wires and diodes / resistors or
whatever they are ?
thank you all very much in advance
the help is priceless and very much appreciated

Disconnect it and join the 2 wires.
The wire going to the old distibutor should have been a green one which
goes to the -ve on the coil.
The new distributor will be electronic and will need a feed from the
positive on the coil, black (the same wire you removed the resistance
wire from) and an earth, brown, as well as the original green.

cheers jim,
regarding the resistor wire which is as you describe, with bullet
connectors, do i just disconnect it and leave it? or disconnect it and
reconnect the 2 wires where it joined?
looking closer at the starters it looks like the terminals are numbers
so ill whip the new one off and trace the numbers to the old.
cheers for your help.
by the way, having done this swap yourself before, do you have any
guidance as to what to do regarding the distributor?, i only had one
wire going to the old points distributor and have no idea what it does
as it fell off and the battery is out the car, will this be needed as
part of the 3 pin conection on the new distributor?
chers again, youve been a great help with this project,

The spade terminal on the old one is the one from the starter contact
on the ignition switch, this is the one you need to connect to the small
terminal on the new starter.
The other small terminal on your loom goes to one side of a resistance
wire between the ignition switch (the main ignition circuit not the
starter circuit) and the ignition coil.
On the OHV engine the ignition coil is run via a resistance wire
normally and this is shorted out by the contact in the starter motor
when the starter is turning to boost power to the coil.
You can't use this setup on your new starter so you need to change the
coil to a CVH one (the OHV will overheat) and remove the resistance wire.
The resistance wire is normally pluged into the main loom via a couple
of bullet type connectors near the coil.

Hi all.
so ive got the xr2 engine in and bolted up, ive started to unravel the
wiring I pulled out the way to clean and repaint the chassis and have
started to try to put it in the right places.
thinking the original OHV starter was probably a bad idea I went down
the scrappy today and plucked one from a k reg mk3 with a CVH in it.
its bolted up ok and looking at the sizes of things the OHV starter is
too long to fit as it would foul my new super sexy 4 branch manifold.
not paying much attention I bolted it on without looking at the
connections and now im puzzled by the terminals, both have 3 terminals
but the OHV has a spade and the CVH doesn't, to demonstrate here's a
pic
OHV

anyone got any ideas which wires go where, I know the bigger of the 3
go to the main threaded lug but on my wiring on the car I also have 1
spade and 1 funny push on rubber coated connection similar to the type
that goes to the coil .
next on the agenda it the distributor, the old OHV had just 1 wire
hooked in somewhere, something to do with the points I think, but it
sort of fell off as I touched it, the new dizzy has 3 connections like
so
[img]http://i120.photobucket.com/albums/o192/jindal/DSC00163.jpg[/img]
so question here is what do I have to wire here? I imagine its a whole
new loom as such but if somebody know just how to connect what to
where that would be a great help.
also on the subject of the coil and switching from points to
electronic , what needs to be done here? I understand I will have to
swap the coil for a higher output type which is fair enough but what
about the ballast resistor? which I assume is the funny grey wire
about a foot long with 2 rubber connections at either end? anyone got
any suggestions here?
your help will really be appreciated and im hoping to get the car
running soon
p.s. when I disconnected the gearbox selector I marked the shaft to
clamp position, I bolted it up today using the marks as reference and
hey presto, it all works.
im happy with that :D- Hide quoted text -
