Hi there does any body no how hard it is to change a wiring loom as my 94 corsa isnt an ecotec and i would like to put one in thanks

so your car must be an 8 valve,you say ecotec but which one which ever you are going to fit you will also need the ecu to match the engine.the wiring itself is simple just transplant the loom off the same car as the engine comes out of
