Haltech 750 plug and play harness for Honda obd1 harness

This product is just for the wiring harness, it does not include an ecu. Option one Includes a two wire female clip that will be installed into the CAN wires, this will allow you to plug any devices that run off the CAN network such as a haltech wideband setup. https://www.rcautoworks.com/collections/haltech/products/wb1-bosch-single-channel-can-o2-wideband-controller-kithttps://www.rcautoworks.com/collections/haltech/products/haltech-ic-7-colour-display-dashOption two is for our plug and play vtec relay kit, in order for vtec to work you will need to wire a relay into the system. An OEM ecu sends positive volts to activate vtec where Haltech sends a ground, this will come with a single wire connector that will hook inline to our harness, and the other side will go to the relay. ****IMPORTANT**** you will still need to run one power wire from your chassis to the relay. We include a full diagram showing you how to do this. If you email us what chassis code you're running ( eg, ef, dc ect...) we may be able to provide a chassis pin out for the best possible area to tie into power. Any questions feel free to contact us before buyingRCautoworks@gmail.com708 599 5884M-F  9am to 5pm central standard time
