wires

[karlmk3]

sup guys where do these wires plug into under the dash

 

[RockPaperSwoRD]

they look like body plugs. take off your glove box and the plastc cover on top of it and there shoudl be your heater core and youy should find those plugs around there

 

[karlmk3]

I did that but I don't have those plugs on my car what are they 2?

What year is your car? Those plugs are designed to plug into a 90+ year car. If you have an 89 they likely won't work.

For some reason I can't enlarge your thumbnail pic, but from what can see; it appears your holding the 14 wire plug and 2 wire plug that come off the same harness that plugs into the little white climate control box. Both of which plug in right behind the glove box. If the climate control box is connected, give that plugs harness a good tug and follow where the missing plugs are trapped. When reinstalling my dash, I too was having difficulty locating those plugs. I ended up going to the junkyard and looking an MKIII there to see where the wires ran. Mine were found to be trapped between the upper right of the dash and the dash brace.

Fyi, my car is a 90T; so I don't know if you even have a climate control box on your vehicle. If you don't, I wouldn't worry about those wires.

The gray plug is the B3 plug, which you won't have under your dash if you don't have ABS or TEMS etc.

The white plug is B2 and is for additional accessory wires 90+ car (more TEMS stuff, cruise etc).

So neither of those plugs are actually needed if you don't have these accessories. You only need M1 (gauge wiring) and B1 to run the car.

I got the harnass ran and the ecu in the stock spot under the glove box, I was wondering why one plug has 16 wires and the other has 12. NOT the options plug!

EDIT: Sorry, it looks like you might have the right plug under your dash...do they just have different numbers of pins or do they not plug in. (I'm trying to determine what wiring you have in your 89 since it varies.)

 

[karlmk3]

The ecu harnass has 12 pins and doesnt plug into the body plug it has 16 pins. The smaller plug doesnt plug in either and has more pins.

Alright, then you've basically got what's considered pre 89 wiring in your car. Your 1jz harness is wired for a 90+ car, so none of the plugs will match up as you've noticed.

You will need to have the harness rewired for a pre 89 style car or make an adapter for that harness to plug into your car.

So when i make the adapter for both plugs do i leave the xtra wires?

Well, some of the extra pins on the main plug go to different plugs. For example, the 90+ B1 plug has the progressive power steering wires included in it. The 89 progressive wires are on their own plug, the one you have pictured with only two wires going to it.

ok can some one give me a chart of what the other wires are that are on my body plug or tell me so i can wire them in correctly

 

[karlmk3]

theres got to be a wire diagram somewhere

 

[JonoTurbo]

There are wiring diagrams for the 1jz harness to 90+ plugs, and one for 1jz harness to 87-89 plugs. From those two diagrams you can figure out what has to be done, but there is no diagram for it.
