Haltech Ignition Harness Overview
The Haltech 13B Terminated Harness has two ignition harnesses available
Please specify at time of purchase.
Haltech LS1 Ignition Harness (Supplied with kit # HT051203)
The Haltech LS1 Ignition harness is designed to be a plug and play solution when
used with Haltech LS1 Coils ( Purchased separately, order as part # HT020102).
With the additional purchase of four LS1 coils this harness will simply plug in.
The use of Haltech LS1 Coils with your engine package will save you time and money,
as these coils have inbuilt ignitors, so ignition modules will not need to be purchased.
