need clarification here please.

Are the described reisitors? required at all???

Looking at the 7MGE engine from the radiator side, there is a resistor? mounted to the right and left side of the body/wheel well.

The left one appears to have a relay and resistor and the wiring appears to be separate of the engine harness.

The right one is a resistor only. The wiring is in the harness?

I can not find wiring from my donor harness, which is on my engine, to connect to this??


Thanks

im not sure if its the same on a 7mge as it is on the 7mgte, but the resistor on the right side(i believe it has a 4 wire round connector) is the injector resistor. ill have to check about the left side

the harness I am trying to use does not have this connection or even the wire to the connection.

Is the injector resistor required to be installed and wired up??

the injector resistor is required. On my harness, the connector for the inj resistor is by the diagnostic connector( just before it)

I still do not understand this.

I took apart a hacked harness and it is just like the one in my truck. The black orange wire at the end of the injector run does not appear to connect to anything like the injector resistor plug.

Do I need to connect a resistor? If so can some one shed some light on this?

thanks

so you don't have a 4 wire round plug near the diag? If not, you will need to find one. It sounds like you might be better off finding a new harness. You can probalby get one for $50-$75.

thanks for the reply

So it sounds like I need an injector resistor?

doing some digging to determine if the first harness I was trying to use was good.

It appears that 7MGE had an injector change...

<'88 NA injectors are low impedance 260-320cc/min (300?)
<'88 turbo injectors are low impedance 404-456cc/min (440)

'89+ NA injectors are high impedance and flow 276-340cc/min (320?)
'89+ turbo injectors are low impedance 404-456cc/min (440)

It is possible to use high impedance injectors in a low impedance system. However it is NOT possible to use low impedance injectors in a high impedance system (simple circuits->too much current flow = fried injector drivers)

.......

my understanding of this is that later years 7MGE do not have a ballasted resistor for the injectors. IMG I wasted some time then. Crying or Very sad
