MR2 Plug & Play Harness

Have you been wanting a TEC3, Haltech or other EMS but have been afraid of the wiring job? Don't want to spend the $1000-$2500 a performance shop will charge to do an installation? We will take the EMS wiring loom and make you a MR2 stock engine harness to EMS harness that is as plug and play as is possible. You tell us what options, inputs and outputs you want, send the EMS harness and we put it together and send it back to you inside a week. The cost of fabricating the harness is $300. We send you back a harness that you plug right to the stock connectors in place of your stock ECU with one or two extra wires that you run to sensors that are not on the stock engine. All your stock accessories will continue to run and work (Tach, A/C, PS, Cruise, ABS). Should you ever decide to sell your MR2 and take your EMS with you, the car will be stock again. You can get a set up that is 100% street legal running with a stock ECU and just switch to the EMS to be ready for serious power at the track or the drag strip. You can have the EMS control your nitrous, water injection or boost. Tell us what you want and we'll show you how it can be done.

The total costs work out like this depending on your particulars:

  • $300 for harness design and production
  • Extra $100-$250 if you want a rush job (depending on how rushed, we can be convinced to turn it around in a single day).
