mkiv 550cc injector help on wiring (searched already)

86_sports_1jz · 01-08-2009, 01:29 AM

okay im upgrading my injectors another step and have searched for wiring diagrams for installing the mkiv 550cc injectors into a 1jz but all my searches came up with different diagrams from eachother. can some one give me a wiring diagram that they know that works for sure or can they point me to one? i don't want to hack things up using a incorrect diagram.

thanks, toua

I don't think you searched good enough :

look at the first diagram on the page and that is how it will be wired through the 7m resistor. Don't read too deep into the thread or you will confuse yourself.

i searched and got those but there was couple of pics on that thread and i got confused about which one to use because i didnt know which one would be the right one. do i just connect the the black and orange wire from the 7m resistor to the black and orange wire on the b1 connector, then the b1 connector will split the connection up accordingly or do i have to wire them up and split them into 6 wires manually? thanks again for the reply

Just go to that thread and look at the first picture pposted by "jza71" .
Wire it just like that . It should be like the one in the second picture there.

Basically, only cut the black wires from the injector clips. Please leave at least 3-4 inches of wire on the injector plugs where you cut that black wire.

Then, from the harnes /ecu side, bundle all the cut Black wires into one end and connect them to the Black/Orange wire on the Resistor plug.

From the resistor, the 3 other wires , ( black, yellow, red) will all be connected to the injector clips ( where you cut the black wire from ).

You will need to pair up the injectors for each wire .
Solder two pieces of wires to each colored wire as in picture.

Basically you can wire each color to these sets of injectors : eg how I did mine

Injectors 1-4 to Yellow
Injectors 2-6 to Black
Injectors 3-5 to Red

Solder and heat shrink is your best friend.
Good luck
