the distributor will only go in with a very small margin of adjustment, so set the engine to TDC NO. 1 and stab in the dizzy with the rotor towards no. 1. then run all the wires to the correct spark plugs, all the wires for the odd cylinders are on the drivers side of the dist. and visa versa. you can't actually set the timing to keep the CEL off but the ecm will adjust the timing to as close to perfect as it can and then you need a scan tool to set the CMP retard, so the light will go off... clear as mud?
