It offers 5 analog inputs (e.g. for TPS, clutch position, engine temp, etc.), 2 digital inputs, and 2 general-purpose outputs. All MaxxECU models, including the MINI, also feature a fully configurable CAN bus interface, allowing them to send\/receive data with external devices and ECUs. This means the MINI can easily communicate with your engine’s aftermarket ECU or OEM CAN network to gather critical signals like RPM, throttle position, and more. It even supports some OEM CAN protocols and OBD-II messaging for broad compatibility. Must use 500k bus speed. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMotorsport-Grade 8HP Wiring Harness\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTo complement the MaxxECU Mini, this bundle includes a \u003cstrong\u003eSeems Legit Garage harness\u003c\/strong\u003e that makes installation straightforward and \u003cstrong\u003eprofessional-grade\u003c\/strong\u003e.

These high-end materials meet or exceed OEM and military specifications, providing excellent resistance to heat, abrasion, fluids, and vibration. This ensures the wiring can withstand the harsh conditions of engine bays and track use without issue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-Play Design:\u003c\/strong\u003e The harness comes pre-wired for the ZF 8HP, drastically \u003cstrong\u003esimplifying installation\u003c\/strong\u003e. It’s essentially a \u003cstrong\u003eplug-and-play solution\u003c\/strong\u003e, saving you hours of wiring work. All critical links between the ECU and transmission (such as CAN communication and power supplies) are complete.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeutsch I\/O Pigtail:\u003c\/strong\u003e For any additional inputs or outputs you want to utilize, the harness includes a \u003cstrong\u003eDeutsch connector pigtail\u003c\/strong\u003e exposing all the MINI's extra I\/O channels. This makes it easy to integrate things like paddle shift buttons, a brake pedal switch, an ignition cut trigger, or analog sensors – \u003cstrong\u003ewithout any splicing\u003c\/strong\u003e. Simply tap into the provided pigtail connector to add whatever signals your setup requires.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWith CAN:\u003c\/strong\u003e Simply tie the MaxxECU into the vehicle’s CAN network (500kbps bus speed required) and the needed signals (engine RPM, throttle position, etc.) can be shared digitally. The MaxxECU’s flexible CAN configuration means it can communicate with nearly all aftermarket ECUs and many OEM systems to grab the data it needs or to broadcast transmission data out. For example, you can have the MaxxECU receive pedal position, engine RPM, and vehicle speed from an existing ECU over CAN, and in return send out gear indicator or other data to a digital dash.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWithout CAN:\u003c\/strong\u003e The included harness has you covered with analog wiring. You can wire traditional signals directly into the MINI’s inputs – such as an engine RPM signal, throttle position sensor, brake switch, temperature sensor, etc. The provided Deutsch connector pigtail gives convenient access to these inputs and outputs, so you can easily hook up the basics for transmission operation. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eIf your vehicle doesn’t already have a active CAN bus, \u003cstrong\u003ewe include a “short bus” CAN bus \u003c\/strong\u003eto create one. This has the proper terminating resistors to form a CAN bus between the MaxxECU, the 8HP’s TCU, and any optional CAN device like a digital display. This is especially useful on vintage cars, you can add a CAN-based dash to older cars using to display the physical signals you are sending the MINI. \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Seems Legit Garage","offers":[{"title":"Default Title","offer_id":47879177568443,"sku":"SLG-8HP-TH","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/9556\/2683\/files\/image_26d95378-a466-468f-8ec7-bcacd303d324.jpg?v=1779792722","url":"https:\/\/drifthq.com\/pt\/products\/slg-mini-8hp-transmission-harness","provider":"Drift HQ","version":"1.0","type":"link"}
