I Need A Schematic Diagram On How The Injectors Get's It's Power. From Where The Wires Get Power Etc. Does Any 1 Knows Where I Can Get This From?

front primary : brown (-) and light Green (+)
front secondary: brown w/ white stripe (-) and light green w/ white stripe (+)
rear secondary: brown w/ yellow stripe (-) and light green w/ red stripe (+)
rear primmary: brown w/ red stripe (-) and light green w/ blue stripe (+)

the grounds connect to the soleniod resistor if you have low impedance injectors, the postive comes off the ECU for all. also, the grounds are connected to a black w/ yellow stripe wire. that may or may not have the soleniod block with it. that goes to the main relay.

I Forgot To Write Down What Kind Of Car I Have. It's A 88 Tii 13b S4. I Don't Know If The Wires Change!!

Whizbang

good! thats exactly what i gave you!

Whizbang

oh, you wont have the resistor soleniod though
less to worry about!

Factory service manual links are in the FAQ. All this info is already there.

I Want To Test The Continutity On Each Wires That Goes To The Injectors That Is Why I Was Asking For The Diagram. But If You Can Give Me The Verbal Wiring I Can Do It.

Just pull the small plug off the ECU and check for 12vdc on the pins 3C, 3E, 3F and 3H. Key to ON, please.

One side of the injectors is feed 12vdc from the MAIN RELAY, it passes thru the injector to those pins on the ECU where, IF the CAS is turning, the ECU will pulse a ground to those pins at a given time, measured in miliseconds.

So, you see, all you have to do is put the key to ON and pull the plug off and check for approx 12v on the plug. Not the ECU side. Done.

There is a online fsm for the 88model. It has the wiring diagrams. It shows the wiring. It shows how the plug is numbered.

The download is free.

Hailers, Where Can I Find That Wbsite. What Should I Type In?
Should I Type In The Search Engine " Fsb 88 Rx-7 Diagram" ?

So Confusing To Read. You can find FSM at http://www.iluvmyrx7.com/ as stated in the faq.

I have a mirror copy at the link in my sig.

Here's a jpg of part of a page that I got from a free download:

What's so hard about removing the small plug from the ECU and looking for 12v at each injector plug?
