Hi
I have a Elise 111s and am putting in a Honda K24 engine.
The only thing that is left on the project is the electronics, we have 4 cables that we don�t know what it is.
Can anybody help me,
Here is a pic
2 of the cables are green
1 is white/blue
1 is Orange/purple i think
Here is a pic
Does anyone have a electronic diagram for lotus/honda
K24 conversion aren’t common in the UK.
I’ve got a few Honda manuals, do you know know what car the engine came from? CR-V or Accord are normal, the engine number would help here.
Could you take a couple of photos of the plug the wires end in, end on would be most useful, from the wire and connector sides, most of the manuals show the plug configuration and pins.

Hi
It�s a honda accord engine. We have all the honda workshop books. So the honda cables isn�t any problem.
The problem is from the lotus side. We don�t know what these 4 cables are.
The engine have a K20 (hondata) ecu and harness. So it will be the same as putting in a k20 engine.
So if anyone has a diagram for Lotus S1 to K20 it will be of help to us.
Best Regards Tomislav
Ah ok, i’ve got the S1 Manual, i could mail you over a copy if you pm me your mail address?
In general green is power from the ignition, purple is power from the battery, should be easy to check with a multimeter or did you mean purple with an orange stripe.
Do you know where the blue plug went on the VHPD?
Hi

I ment purple with an orange stripe. Do you know what it is?
The other one is white whit blue and we sold the engine so i dont remember where it was 
iam going to look at som pic taken before we took out the engine
We didnt have the vhpd engine, it is a 111s whit the vvc engine
I’ve not recieved your mail address.
The manual has elise diagrams too, so should be of help.
Just having a look myself there’s a blue connector labelled as Engine Harness Connector 1 (EHC1) (section MH Sheet 15) which is a 13 pin connector that looks like your photo to me. You can get the pin numbers and check them on the wiring diagram, it should match up with wire colours.
At a quick scan the pins seem to be (please check this, i’ve just spent a few minutes have a look):
EHC 1 (pin, colour, connection)
1 W Ignition (unfused)
2 WB Tacho (to instrument pack)
3 WR Starter relay coil
4 NS Bridging link for Cobra Immobiliser

7 NY Alternator

10 BW Lucas Alarm
11 YR Lucas Alarm
12
13 US Cooling fan relay coil
