MAP (Mitch's Auto Parts) have developed this handy conversion harness aimed at those of you looking to swap the holy grail of 4-cylinders (the Honda K20/K24) into your MR2 Roadster ZZW30.
Using a 'Plug and Play' approach, MAP have taken care to use OEM type connectors to allow you to pair the Honda K-Series engine loom with the interior harness of your MR2. This harness requires modification to only 2 wires to enable you to start the car (instructions included).
This is the 5th revision of this harness now and provides full OBD2 functionality and an adapter for O2 Sensor. This 'street' version has no provisions for A/C. If you would like functioning air conditioning in your K-Swapped Toyota MR2 there is some additional work and cost involved to do so.
Plugs directly into Honda ECU so perfect for a wide range of options such as; Honda ECU with Immobiliser Bypass, Hondata KPRO/K100 boards, Haltech Plug-Ins, Link Plug-Ins etc.
Sadly, as the Toyota ECU is no longer present after the installation of this Harness and your chosen management, the Oil Pressure Light, Battery Light and Water Temp will no longer function on the dash. We are currently working on a separate gauge which can independently display this information.
A great product which removes a big headache for many people considering the K20/K24 Swap into their MR2. The MAP Harness Adapter can potentially save you hours of research and wiring and get you behind the seat of your K-Swapped MR2 in no time at all.
