V10 to 7.3L Excursion

Small update

I started retracing wires to get the oil pressure and tach working when i noticed one wire is WH/PK and the other is WH/RD. Sure enough I got them backwards cause they look nearly identical. I switched them and they both work now. Except the V10 tach reads high. at 700 or so RPM's it read out 1000. the ratio seems to stay pretty constant. I tried cutting the ground for the v10 tach select but that did nothing. I tossed the diesel cluster in and it read accurate so i will need to grab a diesel cluster with about 140K on it to keep things right.

I also found the FR headlight blew out. When I dug into that part of the harness I found there were 2 GR/OR wires and I got them backwards. Now I have both headlights and cruise control. Besides the a/c line and the gas filler neck I am done with the conversion now.

The cluster isn't the digital odometer, right? You can pop out the odometer and put it in another cluster. I have done it a few times. And I have a couple diesel clusters laying around if you need one.

I think it was digital, but thanks for the info guys. Unfortunetly I sold the Excursion though. A guy came along and offered the right price on it. I miss it already, I might get another one in the future cause I already regret selling it. I want a 2wd next time though, and a manual trans, and a ......

If the right deal came along for a manual 6.4 for my excursion, I would be really tempted. Manual is cool to me just because you don't see it much, especially in an excursion. :rockon:

It seems like a lot of work I wonder how much a shop would charge

A shop would charge so much that it wouldn't make sense, you could just go buy one for 15-20 grand

I would do the manual swap into a ex for around 10k. That would be including the price of the trans, t-case, pedals, floor hump, etc....
