A search turned up nothing useful...

My 87 T2 are the injectors low or high impendence?
I thought 86-87 were low and 88 and newer were high impendence...

I was going to buy some low off a guy for my car and he swore up and down that what his Low would not work. So it got me thinking...

 

depends on what ECU you are running,along with the harness.
the answer of Course is in the FAQ stcky on the top of this Page.

 

put a multimeter lead on each pin of the injector. simple.

 

86 - 87.5 is low injectors. The wiring harness will have the resistor pack on it. 87.5+ - 91 will be the high imp injectors and will not have the resistor back. You can use low imp injectors on the high imp harness but you will have to solder in resistor so you won't fry the injectors or ecu. I have a high imp s4 harness and I will be using 91 high imp primaries and 720 low imp secondaries with resistors.

 

if you open the hood (i know so much work!) you can see the resistor pack for the injectors, even under the stock airbox. or not

 

Attached a jpg of the item in question. Looking down........wiper fluid neck can be seen on the left to give you an idea of where it is. This guys got a cone air filter to the right in the jpg.

 

I definately have the resistor pack so like I previously thought I need Low Impendence injectors...

The guy had a solid argument, He swore that only 86-87 N/A used Low. Turbo and 88 and newer were high, so it got me second guessing.

I should not have doubted myself. lol

Thanks

Written in error. Deleted my words here.

 

The change from low to high impedence injectors happened in mid 1987. The chassis numbers 550168 and earlier used low. The chassis numbers 550169 and later used high. See attached jpg out of the parts fische.
