the second on the block goes in a splice and then one goes to the block on the firewall the other 2 go to a smaller ring and a push on terminal

Post by: aussie on October 20, 2009, 08:00:29 PM: yup Flamingbig10 mention that in an earlier post i found out the purple wire that goes to the soilniod does not have 12v cranking so i checked on rear of the fuse box where the purple wire comes out and i dont have power there either i checked fuses all good i made sure it was in park still no power i checked in neutral nothing its stumped me
