To make ordering easier we categorize harness’s in different groups. The price increase as level increase but the installer will save time on his side. Spitronics mostly supply Level 1 and 2 due to the product being sold in the DIY category. Some third party dealers may supply the Level 3 & 4 but Spitronics will not carry the guarantee on workmanship.

Level 1

Basic harnesses. These harnesses’ come with a connector and the wires that go in them and predetermined lengths. The wires are marked and the colors are found on the drawings. Each installer will customize these harnesses in the car to his liking. He will add relays and fuse box wiring himself and supply all the power wires to the components like coils, injectors, fuel pump etc.

Advantages

• Cheapest option.
• Easy to customize in the car

Disadvantages

• No fuse boxes included
• No power wires included
• Long install time

Level 2

Premade complete loom untidy. These harnesses’ come with all the connectors and the wires in one loom with predetermined lengths. The wires are marked and the colors are found on the drawings. Relays and fuses are wired into the loom which will save installation time. The loom is not tidied up yet to leave the installer the option to reroute GP output wires to different locations. The heat shrink on the connectors are supplied loosely to be tidied afterwards. There is also a roll of cloth tape provided to make all wires neatly covered.
