Started taking the Ecotec out of the Astra today. First the wiring loom, what a nightmare getting the Ecu out. Some smart *** rivited the ecu to the black casing in the footwell up under the dash. The other problem was that the ecu multi plug is under the ecu. I couldn't get it past the ecu so i could take it through the hole in the bulk head. Disconnected all the coolent pipes, downpipe and exhaust. So tomorrow the engine will be out and the rebuilt C20 LET in. Will hopefully just have the wiring to do on Sunday then running in period.
