How uncomplicated it is actually will depend upon your pertinent skill and expertise stage. You must sorce the right ecu header, devise a means to attach wires towards the pins over the back again aspect (commonly experiment until finally a decent fitting crimp pin is identified), attach wires, create a mould to "pot" the connections and insulate the bare pins, reverse engineer the manufacturing facility pinout - such things as which circuits are live on a regular basis - which are Reside only with ign and many others, normally there will need to be compact circuits included within the adapter loom to produce factory relays and so forth perform properly.
