hi guys, i bought a set of 1380cc injectors and HKS twin power (no harness) for my FD, i wanna have them installed myself, just wonder if anyone know any link or tips on the installation so i can avoid some common mistakes, thx alot for your input.

it's just seems very time consuming for the injectors and looks like i have to remove all the throttle cable, TB and UIM...kinda sucks.
