Wow, this is an incredible thread!! Just what I was looking for (actually, someone pointed me to it!!).

I really want to do this to mine. I'm curious though, is it illegal in the state of Nevada (or anywhere) to swap out the cluster with one that has different mileage? Also, do I get the same sending unit? Or is there a different SR5 one? Is it just to turn off the light?

 

not sure if its illegal or not i have done it on my rigs but i also plan on keeping them. you will need the oil pressure sending unit from a sr5 car . I priced one from car quest and it was over $50.

 

I just did this swap to my 86 pickup, and have a question. My question is about the fuel guage, is it suppose to return to empty when the key is turned off or does it only work as the fuel in the tank is used up? I have 3/4 of a tank when I changed the cluster and the new one went to 3/4 but it does not return to empty when key is turned off as the old cluster fuel gauge does, so i am wondering how the new guage works. Don't want to leave it like this and find out the hard way, maybe someone with an SR5 can tell me how theres works?
Thanks for your help

 

Bump for reading on a computer that isn't dial up!!

I swapped in the SR5 cluster, and the fuel gauge didn't return to empty with the key off like the old one, so it's normal.

 

I wish my oil pressure guage would read right after the swap, once warmed up at idle it is at or near the bottom of the guage and only gets to halfway at best when driving. It's a rebuilt long block and the oil idiot light never came on before the swap, I swapped sending units again and it came up a bit more....anyone know how far they thread in?

 

thats normal


welcome to toyota gauges

 

WOW...greate write up..what ehh heck of a difference.

 

Great thread, this sould be made in to a review, but needs picture links to be updated

if only i could find an SR5 cluster

 

Dang... I figured this thread was long dead. I just started deleting some of the photos off of my server yesterday. It was getting too clustered.

 

well im glad to see some are back up

 

Don't delete them yet...I have just ordered a different cluster

 

Well, since this thread has been re-born, i have some questions.

I have an 86 4Runner produced April 1986. My coil/ignitor assmbly has 3 green plugs coming off of it. One with 3 short wires that runs across the engine to the engine harness, one with 2 short wires that disappears into the body harness by the coil, and the third with two long wires that runs to the distributor. Can I swap in the SR5 cluster without adding any wires, and only changing the oil sending unit?

I have heard conflicting reports about a split in 86 or 87 with swapability, and i'd just like to clear it up once and for all. I do have access to a 4cyl 5spd SR5 Cluster btw, so I dont have to worry about V6 or automatic differences either.

 

buuuuuuuuuuump

 

I just did this swap this week end. I changed the oil sending unit but the gauge still does not work and neither does the tach. any suggestions?

 

Are you sure the oil sender works? I think there is a thread that tells how to independently test the sender and the gauge.

 

MODS: Why is this in the 95.5+ section? Can it be moved?

Nice Job on the write up and tech. I have wanted to do this for a long time but never got around to it. Now I'm not sure about "adding" to my truck as it might not be mine for long.


Oil Gauge and sending unit test procedure 93 FSM on pages 9 and 10 It also has the test procedures for the rest of the guages and senders. Still should work for the older units.

 

Someone posted they used Teflon sealing tape on the oil pressure sender. That can cause low oil pressure readings as sender needs to ground to block.
Mileage changes are easy if you have strong hands. The ten and hundred thousand wheels are easy to force to any reading. Do the ten first then the hundred. Your looking for trouble rolling the thousand wheel.
Only hard part of this swap is the unhooking the speedometer cable. Unclip the Speedometer at the firewall ( engine side ) and push in an inch of slack.

 

I just did this swap. Everything works but the Oil pressure. BOught a brand new gauge (in the cluster) from toyota ($96!) and it still doesn't work. And yes, I did swap in a gauge-style sensor. I did use one from a 1991 4runner V6 engine tho...so i wonder if those things read differently????
