luckly i got and extra gauge cluster with an oil pressure gauge so I will swap in the new gauge when i do the tach mod.
Thanks

914Runner,

Let me know how the tach works out. We need to hook up one of these days. Along whith the othe Vancouver/Portland wheelers!!

OK, this is getting weird. First before I read this thread I thought my 3.4L oil pressure sender was bad so I got a new one from toyota. I did not put it in when I found out from another guy who did the swap that his gauge didnt work either so I did not want to waste my time until I figured out what was wrong. So now that I read this thread I went to toyota today to get a 3.0L sender, because I wanted to keep my 3.0L complete, fix and then sell it. When the toyota guy handed me the 3.0L sender I imediately noticed that the one he handed me was a one wire sender and the 3.4L sender that I swaped with him was a 2 wire sender. So I figured that I would go home and look at my 3.0L to help me figure out how to wire this sender. When I got home and looked at my 3.0L I noticed that the supposedly 3.0L sender that I got from toyota was different from the one on my 3.0L.
So what the heck do I do?
bwhitehead and COrunner93, do you know what the part number is for the sender you used?
Thanks!

I used my sender off my old 3.0 haven't had any problems. Acts just like a typical toy sender low at idle and normal under load. If you need any pics let me know. I will ask my parts guy at the dealer he is pretty good.

I can think of a few possibilities here, but they are just guesses at best......you're 3.4L might have had an idiot light switch and not a sender....or your 3.4L wiring called for 2 wires, instead of one, which would incorporate the ground wire in it's loop.....instead of using the motor as a ground. Like I said though, I'm just guessing. Hard to do anything else without being there and seeing it.

If you ran the 3.4L sender to your 3.0L gauge though you probably did the same thing I did and burned out your gauge. So don't be too disapointed if the gauge still doesn't work when you get the new sender hooked up.

I am pretty sure I fried my gauge <img src="/forums/images/graemlins/frown.gif" alt="" /> . I am just trying to find out if the toyota parts guy gave me the right sender and how to wir it up?
Thanks

Did this thread go any farther than this??? <img src="/forums/images/graemlins/confused.gif" alt="" />

No, it didn't BUT, there were a few other related threads that also addressed the oil pan and accessories. We were hoping to get this put into the tech articles, but I might move this down into the Toy archives instead. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Well, I will throw in some info here as well, for when this gets archived. The 10K ohm tach mod recommended for the V6 tach also works great on the I4 tach... You do have to turn the calibration pot a tad so it will read accurately.

This would seem to suggest, for you SR5 cluster swap dudes who can't find just what you need, that an I4 tach will work on the 3.0 V6 as well, or vice-versa (same year application of course).

RE: oil pressure gauge, be sure to use WHATEVER year/model sender matches your gauge.

Very nice write up here, thank you for sharing.

Couple questions.

I have the '93 P.U. Planned on this a few years back & for next to nothing. I picked up the 3400, 5 speed trans/transfer case, both axles, drive shafts, ECM & all the wiring from a 96 4Runner. I've been saying, soon as something dies on this truck, I'm doing it. Well clutch went out(finally, can't kill a TOY) & that's close enough. I haven't compared drive trains yet. Since the new rear axle is the locker type I'm considering swapping it as well, or if just doing the entire package would be easier. Any input pro's & con's?
