I have made several threads about the cluster swap. I have also read several threads on the same subject. Here's the scoop from a guy that just finished a swap in a 1984 Toyota pickup.
Parts needed for my swap: 1 NIEHOFF oil pressure switch (a.k.a. oil sending unit). #WA646M Also these numbers will work: OP24821, PS-186, PS138
Not a whole lot to buy, is there? No. The hardest part in the whole job was swapping the senders. One guy said "It's as easy as changing a light bulb". I don't know what kind of light bulbs he's been changing but the ones I've changed were not near as difficult as changing the sender. The problem is space. There's very little of it. I found it to be easier when I removed the oil filter. I needed to change the oil anyways.
I didn't need to change any wires or pins. After I swapped the senders, I swapped the clusters. I'm not saying all trucks are the same. Some may need a wire and some don't. All my blinkers and guages and indicaters all seem to be working properly.
I found another trick. The R&R of the speedo cable. Go at it from the top. It's way easier. Standing on the ground with the driver's door open, hold the new cluster with the right hand and slip your left hand over the top and down behind the cluster. Just pop it in place. I'm not a small guy, I'm 6 foot and weigh close to 400 lbs. I got some big hands. I struggled for about 10 minutes then I positioned myself as described and it popped right in.
On a difficulty scale of 1 - 10 I'd give it a 2. If you can change a radiator, you can do this with ease.
The only thing is that my temp. guage stays at "half mast" until I shut the truck off, then it goes down. I don't know what the deal is on that. Maybe I need to swap out the temp. sender.
