Stand Alone 24x Engine Wiring Harness
EFI Connection builds brand new engine wiring harnesses for the TPI, LT1, and LS type engines. Our 24x stand alone harnesses are built to order so that you receive the best possible engine wiring harness for your vehicle. Installation is very straight-forward with only a few wires to connect to run the engine. A fuse block and fuel pump relay is included. These harnesses are built after being ordered and have an estimated 3 week lead time. We recommend that you contact us by phone to order this harness, but if purchasing online, we will contact you to get specific vehicle requirements. 		Build to Order$650.00
1985-1988 24x TPI Camaro/Firebird Plug-and-Play Engine Wiring Harness
EFI Connection has invested in all of the brand new GM (Delphi) harness components to recreate the 1985-1988 TPI engine harness, but for use with the LS1 PCM. These harnesses are built after being ordered and have an estimated 3 week lead time. We recommend that you contact us by phone to order this harness, but if purchasing online, we will contact you to get specific vehicle requirements. Due to the additional complexity of the 1989-1992 Camaro/Firebird engine harness, we can only offer a new fuel injection harness segment that you will have to graft into your original engine harness. 		Build to Order$750.00
1993-1997 24x LT1 Camaro/Firebird Plug-and-Play Engine Wiring Harness
EFI Connection has invested in all of the brand new GM (Delphi) harness components to recreate the LT1 engine harness, but for use with the LS1 PCM. These harnesses are built after being ordered and have an estimated 3 week lead time. We recommend that you contact us by phone to order this harness, but if purchasing online, we will contact you to get specific vehicle requirements. 		Build to Order$850.00



LS2 coils, a harness to connect the coils, and a method of attaching the coils to your engine
The best deal going is to purchase a used set from a 4.8L, 5.3L, 6.0L truck engine or LS1/LS6/LS2/LS3/LS7 engine. In this way you will have the coils, coil harness, and a bracket to work with. EFI Connection stocks new LS2 type coils, GM# 12573190, at a very attractive price.
