putting LET into nova, thought about it and its going to be best to put the looms and ECU threw the bulkhead first isnt it? is it true i need to find a 1.4 loom/ECU to go in the drivers footwell? as my SPI is in the passengers side.:beer:

you dont need the 1.4 ecu and engine loom as these are replced by the LET loom and ecu. on mine the ecu loom goes through the bulkhead just behind the battery and the ecu is bolted on the inside of the bulkhead.

aw i see what you mean now. you mean the full car loom and not the engine loom. well im not one to disagree with him cause i couldnt say for deffo whether he is right or wrong as i bought my car already converted. if he is right though i may be able to help you out with a 1.4 sr loom from an h reg if this is any good to you. its from a scrapper i bought for the engine and needs a couple of wires looked at at the lights up front as someone seems to have wired side lights to indicators or somethin. dunno for sure as i havent looked at it.

what are the differences between the 1.2 and 1.4 looms. i put the 1.4 engine in the 1.2 shell with very little wiring changes.

cheers

Let me try to clear it up a bit
if you have a 1.2i (with ecu) there are a sheadload of wires that arn't needed in an engine conversion and get in the way
The 1.4 is a carb model so less wires and basic loom
so any you add will make life easier rather than having 2 sets of ecu loom running round the car

Im doing a simialr thing soon, ive got a 1.4 loom and the doner in the garage jsut gotta mate them now
makes life easier if you remove the dash first and you want to get the loom into the car, rather than the engine bay cos you wont get the fusebox though the little hole:p

The lot, there is no engine and body loom just one big loom
its easy enough to do.
so on the 1.2i there is no seperate loom for the engine and car? eg like any of the 2.0ltr engines have a seperate loom fro car and ecu

cheers

as far as i know its quite simple to wire it up. as long as you have a bit of savy with wiring then it shouldnt be much hassle.

i think the basics are

1. main power to ecu from battery

2. ignition(you will need the correct coil and the we bit below it(cant remember its name)). the ecu loom has a connection to it.

3. fuel pump wiring. - thick blue red wire from fuel pump relay to positive fuel pump connection.

i think thats basically it.

im sure if ive missed anythin someone will correct me

cheers

chris when it needs wiring i'll do it for fuel and £10 :D

but it's easy to to yourself.... fit a full 1.4sr mk2 loom (a 1.2 mk2 carb loom will do but you will have to add a couple of extras) all the wires terminate in the drivers footwell in 3 connectors... the wiring is straight forward and can easily be worked out with a cav/cally and nova wiring diagram (i have copys of both in my head lmao)

only extra that will be needed is to pinch the fuel pump feed from the old 1.2i loom it runs from fuse 1 to the fuel pump
