1-4-2-5-3-6 #1,2,3 is on the passenger side. Or firewall side. Oh You're Welcome.
Is this a 3.5 wiring diagram?
Is the 8th digit on the vin an 8 or 4. If it's an 8 will be 1-6-5-4-3-2 and #1,3,5 are in the front.
the vin number is a k or do you need all vin number?
Didn't find a K for a 3.5L. The vin 4 is a Honda engine - the vin 8 is gm, seen a comment about a vin N. If yours is other than 4 or 8 the 1-2-3-4-5-6 should be the one. Wow whata BS. Sorry
If that's the best you can do for us , we may need to contact the local Chevrolet dealership tomorrow.
Thank you for your help.
Well when the manufactures change the engines that much it's hard to keep up. According to 'Mitchel' it's what I found. The 4 & 8 is listed, then I found the 3.8L & 4.3L and they are 1-6-5-4-3-2, then it says all other V-6 engines will be 1-2-3-4-5-6. So I guess that's the best I can do. If it is the LZ4 or the LZE engine, this is correct. That can be found in the glove box, sticker.
