I nned some help. My 98 4runner SR5 that I bought a few weeks ago has ALOT of hack job repairs. A few days ago I dropped the tank to fix a vent tube issue. while I had the tank down, I noticed that whoever dropped the tank previous and did a BAD vent tube repair did not disconnect the harness from the fuel pump before dropping the tank and the connector is broken. I have a new connector. so far all I can find for what pin is what is pin 4 and pin 5. does anyone know or can someone look at theirs and let me know what color wire is what pin in the connector? I have gone through the EWD at the toyota dealer I work at numerous times, I even pulled the paper manual out, both methods only gave me pins 4 and 5

Pins 1,2, and 3 aren't shown because they aren't for the fuel pump, they are the fuel level and low fuel light wiring.

You may double check against the service manual for your specific year.

Thankyou. I have all of that, my issue is determining which one goes to what pin. I have access to toyotas database for repair manuals, and wiring diagrams but all they have is a designation for pins 4 and 5. I had to pick and choose for pins 1, 2, and 3 to temporarily get it driveable until my new connector came in today. Im pretty sure I have them all in the correct positions, I was hoping someone had a pic or could look at theirs real quick. I would rather know for sure that all pins are correct before I lock the pins in the new connector

So you need the pin out for the plug itself?

It shows plug "F10"

I would crawl under mine and snap a pic, but everything is just a brown mess right now. your welcome to come scrub her clean and look at whatever you need though lol.

LOL I know what you mean. the F10 connector our parts department couldnt get but my parts person did some referencing and a 4runner F10 is the same as an older camry or avalon F8. ive got the F8 sitting on my toolbox. im going to wait to put it in until I can confirm I have all 5 pins in their correct location

I do appreciate the rm links but I already have all these. Im a tech at Jerry Durant Toyota in Granbury Tx. I have all the manual and digrams at my fingertips unfortunately, I have been unable to get the info for what pins 1, 2 and 3 were. I think i have 1, 2 and 3 in the correct positions, but I am not positive. fuel guage is working like it should and gas light is not on for the moment (im at half a tank so it shouldnt be LOL)

Did anyone ever figure out the pin connector locations? I was dropping tank to replace pump and before I could disconnect the connector, the tank dropped pulled the pins out. The connector pins are still attached to the wires I just need the locations by color. Thanks.

I need to test my pump, to determine if it works or if i need a ECM or what .

I want to run 12 volts directly to the pump, what pins on the pump plug do I need 4 & 5 right ?If so, how do i tell what is 4 & 5? what color are the wires to 4 & 5?

Here is a good link to the page in post #3 that shows the pin-out. Connector F10 on page 239.

Colors on Pin 4 and 5 are here:http://tacoma.site40.net/4Runner_96-...mci/015ecs.pdf

Pin 4 on F10 is Blue-orange(apply 12V+) and Pin 5 is Black-white (ground-).

The procedure is explained on page 938 here:

Fuel pump connector wiring is.
Pin 1. Leave blank
Pin 2. orange {might be pink} with silver dots (small wire)
Pin 3. Yellow with silver dots (small wire)
Pin 4. white w/ blk stripe (Neg feed)
Pin 5. Black w/ red stripe (positive feed)

One of my customers connector fell apart and I tested this as I reinstalled it making sure gas gauge, low warning light, and fuel pump all worked. Hope this helps someone.
