What did you do to your Ranger today? (Part Deux!)

There should be a tach signal wire behind the cluster. I don’t know what wire that would be on yours, but that’s how I put tachs in my 00 blue Ranger and my 95 F-150. To get a tach in my Choptop I swapped clusters with a junkyard one, lol

I think it's either tan/yellow or tan/white.

No place under the hood?

Look over on the driver side inner fender, near the power distribution box. See if you find a single wire connector with nothing plugged into it. Tan/yellow or tan/white. That would be a tach signal test point.

No place under the hood? When I was looking around the Internet, it mentioned that wire in the dash cluster, but then they also said that feeds from a wire on the “ignition control module” behind the battery. ??? Does that truck have an ICM? I thought it was a computer deal with the six pack coil.

Actually, I’d love to have a cluster that has the tach in it, but I haven’t found one. But probably the real reason is this is the original cluster, and the truck has over 320,000 miles, and I wouldn’t want to lose that on the dashboard. Part of the “over the road“ mystique of the Road Ranger concept.

I’ve had these two tachs sitting here for years, so I thought I’d throw one in quickly that I can maybe take out later. When I’m pulling that big trailer back-and-forth and up to Carlisle and wherever, I think it would be a really nice thing to know what the RPMs are when I’m driving. If I’ve got to take the cluster out to wire it, I may just bite the bullet and buy one, but I hate to change something like that a week before I’m going to drive a couple thousand miles.

I've typed up the process of keeping the stock speedo/odo when I did my '97 Ranger swapping to an Explorer cluster... all it takes is a AA battery and some test leads to jump the stepper motor then pull off the speedo needle after noting the MPH it stops at then jumping the stepper motor again when you put it in the new cluster and put the needle on at the same MPH... not hard really... I have a '97 Mountaineer that doesn't need the cluster that's in it for my plans with it... literal direct swap...

Last week the Money light came on for a P0133, bank 1 O2 switching too slow. Logged with ForScan and sure enough bank 1 sensor 1 was flat.

3 days ago the light went off right after I bought a Bosch 15717 to replace it. Logged with ForScan today again and sure enough it's working again.

Resistance of new O2 is 3.6 and the original one is 4.3

Going to run it till it stops because it's probably going to get destroyed coming out based on how it felt today while I tried to remove it.

Does the resistance difference indicate an issue?
