Speed sensor

[Darren Floen]

Hi everyone.A while back i was asking questions about fuel injection for
a 4.3,being swapped into a Toyota.Well,i have now found a newer engine
to use.I picked up a 91 4.3 throttle body engine,from a Safari van.

So now i need a wiring harness.I contacted Howell and Painless.Howell
says a speed sensor is not required for the engine to run smoothly.Matt
at Howell says that it will only affect the EGR,and not the IAC.
Painless says that the engine will always be stalling on deceleration.

My question is this.How will the IAC motor reset its position if it
doesn't have a speed sensor input?It is my understanding that this
happens when the vehicle reaches 30 MPH.

There is no smog testing where i live.

So,do i need a speed sensor or not?

Anyone know of any good websites dealing with 4.3 swaps and such?

Thanks,
