If all the wires are red, someone has extended them. If you open it up, you should find the normal RED-12v+, BLACK-ground, GREEN-coil-, and WHITE-light.
The "fleet"-
72 Vega HB Drag Car -383/'Glide/9"(9.35@146.19)(5.94@117.28 1/8th)
77 Vega Estate wagon- project(someday)will have TPI305/T-5, S-10 spindles/axles
76 Vega GT- 400/4spd/9" retired from active duty(rusty)
06 Silverado 2WD ex.cab daily
03 Silverado 2WD ex.cab (retired)
06 Haulin' 20ft enclosed car transporter
06 GMC Canyon Shop truck
07 Colorado project( 5.3 4L60e swap)
99 Saturn SL1- wife's car
01 Saturn SC2- son's project
07 Saturn Ion Redline project
and 4 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....

Just a note, some of those older tachs have a lot of needle bounce so you need a resister on the tach feed wire. 47000 ohms if I remember correctly. Available at Radio Shack.

Thanks for all the info. I got to looking and the engine has electronic ignition, no coil. Can anyone tell me how to hook up a tach up to that?

Q: what year is the 305? Is it definitely not an HEI?

On the HEI distributor cap there is a terminal Labled "TACH" right next to the one Labled " BAT".

The BAT should have a wire allready to it ( orangest-pink color)

You need a female crimp terminal on your green tach wire to attach it to the cap's" TACH" terminal.

Sorry, I can't help you with the tach question, but I do have a question for you.

Since you are in Canada, are you putting a real Pontiac V-8 in your Astre?
GM Canada liked to put a Chevrolet engine in a Pontiac for some reason.
Pontiac didn't make a 305 V-8. But, Pontiac did make a 301 V-8 from 1977-1981.
The last year any GM vehicle had a Pontiac V-8 from the factory was 1981. So, it could be a real Pontiac V-8 and you are a trailblazer. Check out this 'unfinished' thread on putting a Pontiac V-8 in an H-Body: viewtopic.php?t=195

They are all letters. Theres a "T" "L" "B" and "G" My guess is that the G is ground and the L is for lights but I have no clue.

T-tach terminal
L-lights
B-battery (keyed source)
G-ground

My guess.
