Does injectors need to be wired in a certain way?
I finally bit the bullet and put my 550 cc turbo injectors in with my Haltech. Problem is my motor was a 88' and these are newer injectors. So I cut my haltech harness and soldered the new conectors on (all the same way, but I wasn't sure if they have polarity).
My car now runs like ****...
Do I have bad injectors? If so that sucks cause I paid like $100 off some asswipe on E-bay.

The map I am running comes from a guy with 550's I've just been using it with 15% increase via the trim ****. 460/550 = 83% (or 17% more fuel). 15% is pretty close and it ran decent like that.
My 460's are low impedance and the 550's are high.

It is barely running. Spits and spudders when I touch the gas. O2 sensor can't even get over 500mV. I tried +50 on the trim **** and it makes a little difference but is still undriveable... Totally lean. I think 1 injector is totally clogged and the other is not far behind.

Fuel Pressure is solid @ 40 PSI (The Autometer Fuel Pressure gauge I mounted on the side of my motor has been very useful).

I have no way to test them. I think I found another set from a better source... Pisses me off they I got burned on E-bay like that.
