just to throw a spanner in the works
you do realise it won't start and run without the key in because it won't be able to read the immobiliser
your insurance company will rape ya for having it fitted as i think it was recently deemed illegal due to legislation over control of vehicle etc etc - i'd check first to be honest
anyway back to the alarm
you do have an ignition coil it's on the end of the coil lead if you follow it back from teh plugs to the dizzy and then middle one out you will usually find em on the bulkhead but the water bottle
oil pressure indicator is operated from the sensors in the housing above the oil filter
fuel pump is igntion activated so i'll dig out the fuse/relay for that one later to
help that
