Our pre-made SR engine conversion harnesses

Here is a few pics of our pre-made harness. We sold the first batch very quickly and have new shipments on order. With this new harness, you do not need to send in your old core, wait weeks for refurbishing and wait longer to have it shipped back. You can now buy our one off Wiring Specialties engine harnesses right off the shelf!

As always, our harnesses are start up gaurentee’d and we offer night and weekend technical support on top regular week hours.
