Another "what the heck is this" thread.
Found this little beauty while replacing the normal filter box with a cone type.
I'd like to create a cold air box there, but am unsure of what that little puppy does.

What a weird *** place for something like that though, you'd think they'd mount it on the firewall NEAR the injectors, hehe.

The resistor is inline with the injectors' power supply and the injectors themselves, so you'd have to bypass it.
Put multimeter across an injector's terminals; if it's low impedance it'll measure ~3 ohms, if it's high impedance it'll measure ~13 ohms.

I dont seem to have that resister in that spot, but do have something similar to the photo bolted up to the front support the headlight bolts to, I thought this was the fuel pump relay or something. So if I dont have the injector resister that means I have to use High impedance injectors right?
Does it matter what ecu you have, such as N318 for example.

It looks like the jpg I have attached. I show it intact and with the cover removed. It's composed of two resistors with the inscription ( 2X6ohms) on each of the two resistors.
One car of mine is a early 87 and I put high resistance injectors in it this year. I just cut the wires ON the solenoid resistor and spliced them all together then reconnected the plug to the harness. Put the resistors on the shelf for future use.
The fuel pump resistor/relay is located where you indicated. Early n/a cars do not have that item.

Okay, more stupid questions. I have just sorced a loom and ecu, the loom has had two resisters added into the ecu loom, the guy I brought it off said that he had two stock S4 injectors and then some 720cc secondaries which he thought was low impedance, this correct
