Reply to Cheeko's Post: Ok I am lost with 7 8 9 10 numbers. I know on drivers side it is Sitting in drivers seat it is 654 from seat to front of vehicle. From passenger seat it is 321 to front of vehicle. My concern is what plugs go where. On drivers side they are criss crossed, passenger side they go straight across and no cross overs. This is where I am lost.

Thanks Cheeko,


Hi, here is a better picture ,sorry for any problems, thanks

First Thanks for your reply.

One more question. From what I am seeing in that diagram no wires should cross at all. They should all come from coil directly to the placed plug in the prospective order. I hope I explained that right, LOL.
Hi, on the drivers side 5 and 6 or the only difference , go by the numers indicated on the diagram I sent and ou will be o.k., thanks, XXXXX XXXXX help please let me know

Ok then I guess I have more trouble then I thought then. Have a MAJOR running problem was told 123 were misfiring From the Code Scanner from Advanced Auto Parts and all plugs and wires have been changed. Soooo. I am at a loss.

Again Thanks for your help and replies. Guess it is time to dig deeper.

Hi, thanks , hope my information helped.
