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"-
77 Vega Estate wagon- project(someday)will have TPI305/T-5, S-10 spindles/axles
72 Vega HB Drag Car -383/'Glide/9"(9.35@146.19)(5.94@117.28 1/8th)
76 Vega GT- 400/4spd/9" retired from active duty(rusty)
03 Silverado 2WD ex.cab (work truck/parts hauler)
04 Silverado 2WD ex.cab (retired)
06 Haulin' 20ft enclosed car transporter
93 Suburban- 350/4L60(retired)
00 Saturn SW2- wife's car
01 Saturn SC2- younger son's project
00 Saturn SL2- daughter's car
98 Saturn SW2- spare
and 3 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.
