This service is designed to make installation a resistor box a seamless process for you and look factory at the same time.

You supply the stock OBD1 Engine Harness to us and we will supply the resistor box and wire it into your factory harness, with a factory look. These resistor boxes are USED pieces but working, they are sold AS IS. Unfortunately with the nature of automotive wiring, I cannot guarantee you or your mechanic will not fry anything so I cannot offer a warranty.

Please contact us with any questions before ordering. When you order, please place a copy of your receipt for payment in the box you ship the harness to us in. Find our shipping address in the ABOUT US section of our site. We will of course hold this order and wait to receive your harness.

As long as payment and information for return shipping is complete when we receive your harness, it will ship back to you within 1 business day from when we receive your order.
