• Description

Also called a Dual to Multi Point Conversion Harness. Required when swapping on a 88-91 Civic/ CRX "DX" Model *Core Required. For D16, B16A, B17A B18, & ZC Swaps. Note: Standard harness does not include VTEC wiring so if you are going to be wiring in VTEC your self or not using a VTEC motor select standard harness conversion. If you are running a VTEC engine & would like for us to add a VTEC sub-harness for you that can be done at an additional cost by selecting swap type below.

You will send us your 88-91 Dual Point engine harness, and the engine harness that came on your new engine and we will send you back your harness modified for your new swap.

You pay shipping of your core harness to us, and select your return shipping method upon checkout. Our address is: Swap Shop Racing 10980 Arrow Route #102 Rancho Cucamonga, CA 91730

We will de-pin plugs where possible, and solder/heatshrink where we cannot de-pin. You will have to follow some easy instructions for further modification at the ECU. There are a few wires that need to be pinned into the ECU plugs. If you choose to use Low-Impedance Injectors (H22A, D16A, B18A Swaps) you will need an injector resistor box.

*What we need from you:
- Un-modified and un-cut 88-91 Honda Civic/ CRX engine harness
- A B16A, B18C, B18A, B18B, D16, or H22A engine harness (must match your engine,). Note this harness while we would prefer to be complete, often times are cut on your new engine that is ok as long as the plugs are intact.
Both are required. If you do not have a core Engine Harness contact us by phone or email.
