Howdy crew,

I'm attempting to install my DL LTD cluster into my EL Fairmont soon, but looking in the "Changing Clusters" document (under EF/EL), the wiring colours listed for the 'lefthand' cluster plug are to suit an EF.

I had a look at my EL 'lefthand' cluster plug tonight and all the wires are in different positions as compared to an EF, plus there are a couple of different wire colours and traces.

Would anyone happen to have the wire colours and functions for the 'lefthand' cluster plug in an 'EL' low/mid series wiring loom?

same layout, different colors.
I made an adaptor for plug and play for these clusters.
Its pretty safe to say you just move the pins over or reshape the male plug.

Hmm okay. I still want to keep the plug original, so if i ever want/need to change back to the original cluster i still can, which is why i want to splice the LTD cluster plug into the EL loom and still retain the mid series cluster plug and tuck it away.

The 20pin plug on the existing cluster is pretty much the same layout as the LTD.
Just need it to be able to stick into the 16pin female plug. the other 12 separate plug is for the door circuit.
you can almost just move all pins across a notch and grind the plug to fit.

Or make what I made. (lower pic)

Okay, i think i get it now. I'm still going to splice the LTD plug into the existing wiring loom though, so...

I know you have said it haha, but i just want to confirm this. The wiring is virtually the same layout (despite different colours). So if i hold the two plugs together and just splice the wire from the LTD plug to the wire that is in the same position on the mid series plug (ignoring blank pin holes), i should be right.....right?

Phew, it took me a while to make that semi-understandable :D .

Hey there, could you send a link to a schematic to make the "plug and play" patch harnesses for both sides of the high series cluster into the mid/low series harness? It appears to be obvious where you got your plugs from: a high series loom, but where do you find the opposite connector for the mid/low connectors to plug into? Failing that would you be prepared to manufacture a set of patch harnesses, and sell/post them?

The right hand plug in the cluster wiring is EXACTLY the same from GLi right through to LTD, you don't have to chop or adapt anything there.

The left hand plug however is a different size, but all the wires are in EXACTLY the same position. If you cut the original plug down to size (ie: take off the unused terminals) it will fit straight into the high series socket on the cluster.

This had me stumped for a while, but i managed to borrow an EL service manual from Ford and made double sure the wire positions on the loom plugs were exactly the same.

So, all is in and working....touch wood! :D

Cheers. Is the right hand side the side that supplies the power for the odo reading? i've got a cluster, and I dont know the mileage. can i hook up the side that works, and see the mileage on this unit before i hook up and modify my harness?

Sure can, unless you have a low series cluster, the LCD won't illuminate, but it WILL be still visible.

As for the above Question, I disected a standard cluster and flogged the female plugs.
I then soldered the 16 pin male plug to it, simple as that, this way I didn't have to cut any wire in my car and was reverse compatible!

You'll also need to wire in the door switches OR add some resistors to stop the flashing door lights.

I have a set of plugs from an LTD, but don't plan on making any plugs,

as above, its actually easier to just gring a little off the male plug and slap it in,

If I come across some cluster parts soon I could put one together and send it over, but really, its not that hard to make urself.

Spot-on, the backlighting circuit runs off the left hand plug, but as krytox said, although very faint you will still be able to see the segments on the odometer, you just have to view it in the right light and angle.

Cheers for that.
I should be ok for that, as this new car is an old cop car.
Its an OPT20- both of my two els are OPT20's, one has 765,000 klms, and the other has 65,000 klms. one extreme to the other!

lcd wiring is on the rhs, but high series cluster into a low series loom might not show the display (illuminated)

as above again, the backlighting wont work.
