went out to swap my radix injectors with some 60lb ones thinking they were a direct swap with this wire connector (see pic), turns out its a lil bigger then the stock gm connector

what now how should i do this swap?? anyone know where to get a direct plug n play connectors without cutting factory harness

thanks

 

I've never seen or heard of a "no-cutting" harness adaptor. Maybe Speartech?

 

oh man i didnt want to hear that..well just got myself a soldering iron, never used one of these any one have any tips on how the hell to solder stuff together

thanks

 

If you don't mind post up your project details. Pictures and such. I might be swapping to 60#ers sometime soon. Which ones are they?

 

It's fairly easy. If they are loose strand seperate the wires a bit and slide the two wire ends together. Mix the wires. Key is getting them hot. I get a piece of metal and place the iron on top of the joint with some fair pressure. Put the solder to the very tip of the iron and make sure the solder FLOWS into the joint and lift off. Make sure and get some heat shring tubing and keep it a ways down the wire so it doesn't shrink up when you are soldering.

 

they are Siemens Deca #107961 high impidence

i have an 05 rcsb (returnless fuel system) i put an lq4, gt2-3 cam,LT headers no cats and true duel exhust, radix with a 2.9" pulley.. we spent like 5 hours on the dyno trying to tune....i maxed out the radix injectors with the 2.9 pulley. truck made 473HP and 483TQ to the wheel with 13.5 TO 1 AIR/FUEL ratio

ill go back to the dyno after i install the injectors and see what she can do

thanks for the tip bro.

 

Thanks for the info. They look like the right height? No spacing of fuel rail required?

 

they like 1/2" taller than the radix injectors swaping injectors is so easy i did the whole swap in like 45 minutes you dont have to remove J-tube.
you can unbolt the passenger side coil pack for extra clearenc going to need six 1/2" longer fuel rail bolts and some spacers and thats it.

i thought it was going to be alot harder than that just by looking at them but once i unbolted the fuel rail the injectors just pop out
