EPAS plugs already in loom??

[Usr117063]

Power and earth plug already in the loom? (loom from 172 cup) Its not connected to the battery though?

@GrahamS

Having done the EPAS conversation myself also, I think the answer to your question is yes, however I have a 182 Cup so not sure if that makes a difference.

 

[GrahamS]

Yep that adds up, my cup was the same. It just needs the power wire running from the engine fuseboard into the r107. You will still have to run the control box and splice the wires from the sensor on the column. That's good because it will already be connected into the diagnostic network and dash light.

This is what the wire will look like although it's the one with an 80A fuse on the end.

I cover doing the change here https://cliosport.net/threads/grahams-summer-172-cup-track-car.768675/page-2

 

[Usr117063]

I was just looking through your thread funnily enough. But I dont understand as mine already has the red connector for the fuse?

 

[GrahamS]

Confusion caused by me! it's actually a brown one. That was just representing the part. Only the brown one from an EPAS equipped car is the right diameter, 7mm^2

 

[Usr117063]

Ah okay! I see it here, but I dont have the extra slots by this relay so I take it Id need the full epas engine bay loom and bulkhead loom? Will just do it on its own power otherwise.

 

[Usr117063]

I just checked and the green connector is for the air conditioning fan which I dont have, so I can just replace it with that?

 

[Usr117063]

Have ordered the loom. I measured the gauge of the wire from the other plugs (red and green) but they are 3.8mm and 3.4mm which seems too small. The wire coming out the fuse holder is the thicker 4.5mm ish guage for all connections so Ill be able swap out the green plug for the brown when It arrives

 

[Usr117063]

Is the mm2 figure of the inner strands only?

It isnt 4.5 its also 3.8, dont know how I measured it wrong

 

[GrahamS]

I'm back. I would use the spare one you have and swap the blade from the brown plug. it's 7mm squared so diameter is about 3mm. It's only the EPAS wire which is 7mm. The other power wires running into the bulkhead connector are 5mm^2

 

[Usr117063]

@GrahamS Sorry for all the questions. Its just Im not sure where the brown plug can go, if its bigger than all the other wires then its the bigger than the wires that go to the battery ( from the fuse box)

Just buy the Ebay kit m8, can have it fitted in half hour.

Side note I've not had chance to sent the abs wire yet but I'm working in it!

Ive got the kit mate this is for the power wire, this way its oem and follows the loom.

No problem I cant (wont) start it until this is all done!

 

[1985michael182]

By half hour I mean you can have your key barrel swapped over. Column bolted in and wired up in half hour!

Main power and earth direct to the battery for better efficiency

 

[Usr117063]

With the right crimp tools and such you can. Ive litterely just crimped my first fitting today

Also this slows down things a bit, very little storage space as well

 

[1985michael182]

Put the window down and dukes of hazard it

 

[Usr117063]

Not a bad idea tbf! I was gonna take the door off before I drove it in but too eager to start

 

[1985michael182]

Does it have wheels on?
Push it outside?

 

[Usr117063]

Trust me if there was an easier way I would do it. Garage is near a foot higher than the ground, the ground before the garage is basically a 45 degree cliff face. One day Ill have an empty costco warehouse to do this stuff!

 

[Usr117063]

@1985michael182 Ive wired up the controller box now bar the black wire (12v ignition feed) I dont understand it, so a wire that is fed power when you turn the key? So nearly every wire under the dash??

 

[1985michael182]

Yea so any 12v ignition live m8.
When you turn on your ignition the ignition live turn the ECU on which then turns the mains power for the motor on the culumn

 

[1985michael182]

Remember some wires are a constant live like door locks, immobiliser all stuff like that. So make sure it's an ignition live and it turns off or you will drain the battery in 12 hours

 

[Usr117063]

Thanks mate. One other thing, that fuse box for the power wire, how is that a fuse? A thin piece of metal? Because Ive taken the dash wiring for the ecu power from another loom and think I can splice them together and do what you did

 

[1985michael182]

Yea you should have an inline fuse. All fuses are just thin pieces of metal designed to be weaker than your cables so if something shorts out the fuse will be overloaded and blow

 

[Usr117063]

Im just gonna up a picture to show you waht I want to do if you think its fine?

 

[1985michael182]

Your main power cables you could have just run straight to the battery, no messing about tracing wires back.

You then have your inline fuse on either the positive or negative line near the battery

Then you need your ignition live and your variable switch wired up and that's it done.

Insulate any potential issues

 

[1985michael182]

If I remember rightly you piggy back the other 5 wires

 

[1985michael182]

Without digging the instructions out of the garage I cant remember what each wire does

 

[Usr117063]

@1985michael182 I have a spare loom, so cut the crimps off to put into the fuse box and crimp, then de pin the factory earth into the plug pic related. How can I crimp the fuse holder ones? I

 

[1985michael182]

Needs to be bare wire and you push them into the ends on the fuse and crimp them to it

 

[GrahamS]

I wouldn't use the brown outer but instead swap it to one which does fit on your fuseboard. For mine I used the double orange connector which there was a space for on the cup. Excuse the incorrect 60A fuse!

You say that but my auto electrician told me to use a 60amp fuse

The factory wiring uses 80a but there was some misunderstanding when EPAS conversions were first done.

 

[Usr117063]

Just turned car on and no power steering. How do I check whats not working? And I put the 12v black wire that powers the small box to the wire that powers the dash lights brightness, too clarify it goes to a power wire that is from a switch or something that only works when the cars on??

 

[1985michael182]

Both your earth and big live wire need to be the same gauge and ideally on their own. Do you have it on the floor or in the air?

In the air, well the rear tyres are resting on bricks the front is in the air. Both of those wires are the oem ones and I know that the earth is bolted down.

 

[Usr117063]

Do I use a multimeter on the power plug that goes into the epas ecu? I have one but dont know how to use it yet

 

[1985michael182]

You wont know if it's working unless you drop it on the floor it needs resistance to work. On your adjustable knob all the ways to the right is full power.

 

[1985michael182]

I gave you my number, text if it's easier
