Im wanting to but a 88 turbo XT ecu in my 89 mpfi touring wagon along with the 88 XT motor, but will keep the mpfi loom intact.   Will the turbo ecu plug straight into the existing mpfi loom or will i have to swap some pins   I realise i will have to add some wires for 2 boost sensors and the Waste gate control as well as the knock sensor,... is there anything i am missing out?     Any help greatly appreciated   Cheers   Gannon.
