hi guys,ive found the best way to get your power cables through the bulkhead once youve found the grommet you want to go through,first thing is you need to cut a cross in the grommet,then get a length of welding rod ,poke it through the hole ,you should see it come out under the dashboard,tape your power cable to the welding rod ,then just pull it through,doesnt matter if you pull the cable from outside in or inside out(inside outs best because you dont need to pull the full length of your cable through) and once youve done that you just need to run the cable through the car. ive been using this method for a lot of years with 99% success.works well for any kind of cable or pipe. hope this is a help.i'll maybe try to post some pictures up when i do my own one,might take a while(NO BROADBAND!!!!!)
