[Diy_efi] The so called "Noid" lights ?

[Bobby Yates Emory]

Mike,

I made one - I measured the resistance of the injector - then a small light
- I added resistors to make the resistance similar.  I wired it in in place
of the injector.  It seemed to work - it would light up about when I thought
it it should.

It seemed to work - but I never got the car running - so I'm not sure this
is a good idea.
