so I'm trying to gain a stock tachometer in my dash of my 1986 dlx with a 20r. I found one from a 86 or 87 turbo 22ret. (questions are numbered below as to reference any answers).lots of photos and can take more if needed. help!!!

^1will it work?

I understand the oil sender for the gauge not the light. haven't burned up the gauge with the wrong sender yet. and I won't.
but I have been doing research.

^2 Is there is only a write up on dlx to sr5 not dlx to turbo?

I went to the junk yard and found a 4runner first gen and it had the sr5 gauge set, missing the speedo and tach. so I cut the wiring harness to the connecters for the gauge cluster (to use as an example and to have the extra pin connectors).
I have noticed a few things different about the connectors.
^3 I read some where else that the turbo gauges need a different fuel sender?

^4 is this just for the digital turbo gauge cluster?

^5 and I shouldn't have to adjust the tach cause it was on a 22ret and not a v6?

cause the board on the back of the tach looks different than the other ones I've seen online it has a split board see photo below 4th photo down. I know to get the lead for the tach off of the negative side of the coil.

^6 should I put every bulb back in the 22ret cluster when I install it?

^7 cause my truck is 22r so no check engine light?
^8 or does every circuit have to be able to make a connection?

^9 why is there a wire on every pin connecter on the cluster but not every pin on the wiring harness plug is full?

^10 I also read that I had to switch all the wires around between connectors?
^11 is this for the digital turbo gauges only?
^12 does anybody have a diagram of the wiring harness for dlx and turbo?
cause all the wires that are on the connecters between my dlx and that 4runner sr5 match exactly in color but again my new gauge is a turbo and the tach looks different than all the sr5 ones I've seen online.





connecter A they both had the yellow and green wires I have since removed the yellow wires from the 4runner connector but my dlx didn't have the three other wires green purple and black.


connecter B is exactly the same


connecter C the dlx has a yellow wire if you look at the pic its the third one from the right and the 4runner doesn't have it. what is that wire?

Did you ever get any of these questions sorted out?
Doing a similar swap into a 85 22r pickup.
Fuel gauge doesn't appear to be functioning and I def don't have a tach wire.
