1994 silverado timing

Could someone tell me what wire you have to disconnect and what deg. to set the timming on a 1994 silverado with a 5.7l. My truck was wrecked and when they replaced shroud they didn't replace the sticker. I thought I would be smart and buy a manual but when I looked in it it said to refer to sticker. So if someone has one of these stickeckes on there truck could you tell me what is says.

Thanks, Don

It should be under the plastic cover on the firewall or possibly behind the glovebax

The timing advance is a single, brown wire that is connected by a plastic two-piece clip. It is located behind a black plastic cover on the passenger side firewall, just above the A\C tank. I simply moved the wire/clip outside of the plastic cover so it is much more accessible when doing timing adjustments.

My 94 has a tan w black stripe behinde the glove box .Disconect & set timing at 0 then reconect wire
