Where does this go?

It's on the loom next to the ecu plug and I'm pretty sure it said something about engine management on it

Could you remove that link, this site is provided by haynes and posting up copytheft material is not going to be liked by them.


What colour wires do you have at the ignition switch, do you have a multimeter?

Ahh right, if it's clicking when you earth that tag then the tag should be earthed. Not sure off hand if it should be to the battery , But there's only ~5 earth points on a sierra anyway. does not realy matter where they are but on the donor there is usualy one at the base of each front door pillar ( although some cars may not have on on one side) one on the steering column support, one behind each headlight and and perhaps one at the battery ( but I can't remember)

Link removed, sorry forgot about that. I have got the book in the garage but was being lazy... Ya I bought a cheap multimeter from wilks the other day to help with this but don't really know how to use it yet :S It mentioned though the other lead going onto the battery neg was some sort of service adjustment cable to do with the throttle I think?

[twinturbo]

The service lead would not be a permenant fixture but a ford workshop tool, I doubt the CFi has one as it would have the efi self test socket.

does the meter say Autoranging, or does it have a lot of settings on the dial. Your looking for DC Volts ( there may be a button to switch from AC to DC. And if it's not autoranging you want the 20V range if it has one.

Connec the black probe to the COM on the meter and to the battery negative. connect the red lead to the V+ if it has one (NOT THE AMPS socket) it may be called something similar.

Then touch the red probe on each of the terminals on the back of the ignition barrel and report back with the wiring colours..

Which May be...
Yellow
Red
Black
Black blue

The one I got looks exactly like this http://www.wilkinsonplus.com/measure...FJ6uMQ% 3D%3D but its made by corelectrics instead of rapitest. according to the instructions it does a dc voltage measurement, ac voltage measurement, dc current measurement, resistance measurement and a diode test. It has a 2, 20, 200, & 500 volt settings. So I set to 20 dc volts and touch the wires on the edis with the red probe but I'm not sure what you mean by putting the black probe in the com on the meter and the battery negative and red to v+?

Rotate nob to 20V


looks like it must have fixed probes?

Black lead to battery negative,

Red lead in sequence to each of the ignition switch positions.

Ya the leads are fixed I guess as they're just wires coming out of the meter with metal spikes on the end so to speak. So just to make sure I've got it right though, I'm testing all the wires that plug into the edis module or the bundle of wires that connect to where the key turns?
