What is this part

[Anthony13]

As above I'm just trying to work out what this part is and what it does to see if I need it at all?

I no it belongs to a 4age 16v but not sure what car it came out of

Resister for injectors

[Anthony13]

Is it needed?

[Skylar]

Yes, depending on ecu and injectors.

[Anthony13]

Hmm okay cos I never got one when I got my loom and engine do you no what models need it by chance cos mine is a 1987 ae82 4age 16v bigport motor it's got that blue sticker on the ecu and my injectors are standard there a grey/bluey colour

[Anthony13]

Sorry that is the model or corolla that my engine and loom came out of

Late model Ae82 with pink injectors

[Anthony13]

Okay so if I've got this right it goes

Early ae82 with 16v 4age has blue/grey injectors and no injector resistor module and map sensor!

And a late model ae82 with 16v 4age has pink/red injectors and has the have the injector resistor module and runs an afm!

And I read somewhere that by doing a resistance test on your injectors it can tell if you need the injector resistance module

I think it goes:

high ohm (10-14 OHM) injectors don't need the resistor module. Ie early model ae82

Low ohm (2-4 OHM) need the injector resistor module. Ie Late model ae82

Does any of that sound right?
