I'm a little lost bear with me, the summit connectors work with ls1 injectors on less than 60#s, but greater than that and you need your style or cut?
The reason I ask is I'm staying N/A, with a FAST 90, i doubt I'll ever need 60's even h/c and etc

The truck style pig tail won't work with aftermarket LS1 injectors... so since you're swapping to a FAST you'll need to swap to LS1 style pigtails to run injectors that'll fit your manifold.

Is there something else you were asking as well?

right, will the summit ones work for 36# ls1 injectors to truck harness? The reason I ask is I would also like to have the ability to return the truck stock if need be, so I hate to cut the stockers off and solder or splice. I'd like to have a simple plug & play & the summit ones don't state multec to ev1

LOL, that's the same thing I wanted to do when I first wanted to do the swap. Unfortunately there's no 'plug and play' for us. You have to splice them in, and re-splice the truck ones down the road if you decide.

kbracing96 found a set of adapters so you don't have to cut up your harness. PM him for info.

I guess power doesn't come cheap or easy, but hey half the fun is getting there.
