EMU help

Just wiring it back together and i have this yellow connector which obviously goes into option 1 or 2, does it matter which? or is there a way i can tell?

There is alo a black connector with power led written on it, i cant see anywhere for this to go?

Cheers

Followed the yellow plug and theres a label for the avcr so have put this in 1. Cant see anywhere for the power led lead, its tied to the same option 1 plug but goes off somewhere else.

Anyone have any ideas. Is this a standard connector when wiring an emu together?

The car started fine but just want to make sure if it should be connected.

That power led plug looks like one from a PC case! I can't imagine that has anything to do with the emu.

Thats what i thought Darryl. I wasnt the one who unplugged the emu so wanted to be sure. definetly cant see anywhere for it to go

You need to trace the other end of the option lead, as they can be used foe a few things, IE wideband input, boost pressure sensor (Greddy), which i would suspect that being a TT/single?

it would need in order to tune above normal boost settings, so look foe a little black box or cylinder with two wires and a small vacuum hose out of it;)

The yellow option lead goes to the avcr and i have plugged that into option 1 on the emu. The avcr is reading boost so all fine. Its just the black power lead connection that im not sure if it was plugged in before Tricky

The "power led" plug is a frig used by lazy and cheap people who don't want to buy an extra option harness. You should find that it will fit in the option connector on the EMU. However it will not lock in place and is likely to come out with vibration.

To find out which way up it goes, you will need to find a pinout for an option connector - the contact with the wire connected will go to the analogue input pin, not the power or ground pins.

Ok thanks. I dont understand what it is supposedly going to power?

Personally i would call it innovative, i have done the same and never had any problems, there are a couple of PC plugs that will fit the EMU, considering the ridiculous prices that Greddy put on a 50p plug and a bit of wire

Stonkin, if you have a look at the software when connected to the EMU it may give you an idea as to what has been connected to the options ports;)

Other than that its hunt the wire I'm afraid.

ok mate, i will have a check. Is it obvious in the emu menus what will control the options ports?

Yellow goes to Option 1 on your car IIRC its the 3bar map sensor

Power LED must be used for an AFR input. I wouldn't worry about putting it back in as it wont be used on the map

Thank you very much Ryan

Hello

I put that on there. It connects the wideband to Option 2 so that you can datalog the 5v output from it. It fits quite nicely and I know my one has been hooked up for the best part of 3+ years without falling out yet.

You can't actually get an option harness specifically for that O2 sensor, and even if you could it'd be something like £30 instead of £0.00p like that connector was.

I can't remember which way it goes up, Stonkin, but you won't hurt anything by getting it wrong, you'll just see 0v in the software.

Once again Ian, many thanks will get it plugged in.When i did put it in to see if it fitted, it certainly wasnt loose.

Thanks guys
