Ah well, hit my first biggish snag. Haven't had anything to do with LS engines before, on a bit of a steep learning curve. Did a lot of looking around and research when buying my coils, whatever I did I was up for a full set as the LSx comes bare. Anyhow thought if I am spending a few hundred would see what's around. Looks like the truck style are the go, and the MSD have got a bad rep in the states but Accel make a nice set that I had read good things about so I got them. Am bloody still kicking myself for not picking up the small loom for them when I did them, before physically mounted them, everything would have been so much easier. Anyhow bought the looms of an LS1, pulled the loom packs out today only to find the Accel are Gen IV style that have a different electrical plug. Dohhh, dohh, double dohhh. Got onto Adam at Precision International (who is on holidays btw that's service!) he thinks he may have the loom I want, (GM part number 12579355) but they arent open until Monday and it will take overnight to get to me so best case I wont get it until Tuesday.
Did however get the brakes all double checked and bled all four corners again and have a great pedal, so not all bad, as the coil pack looms and brakes were the two biggies left, so one out of two I guess.
Just out of reference this the plug comparison, the yellow is the coil and are the later gen 4 narrower style, the top is the earlier regular loom plug, god knows why they changed them.
