splice near horn relay??

what up again bros-need some more expertise por favor. wiring up this heap and got noodle scratchin' about what will work. (and be right) read mad's site multiple times- it suggested "new system" with a "cn1" with the buss bar mounted on the firewall. it's a 69 with a 96 lt1 and new wiring harness from auto wire. my q's are: why can't i just eliminate the "splice" (see pic) and just terminate on the horn relay

Re: splice near horn relay??

Re: splice near horn relay??

this second pic is the old harness. the wire with the blue tape goes to the alt. the wire bundled went to the starter solenoid (new harness wire long enough)

Re: splice near horn relay??

this last pic is of the alt. don't know if it's cs12 or a cs130. the brown wire was taken from the original volt. reg. harness and the blue and white and red wire eliminated. sooo.. if i just make the horn relay the bus bar for the alt. pwr wire and the wire that goes to the horn relay already i'm golden right? i do have the big purple wire from the firewall disconnect going to the starter solenoid too. what u think?

Re: splice near horn relay??

Yes, in a round about way.
You can remove the splice 'if' the red wire goes to the OE battery junction block on the rad support. However, this j/block would be a good power source for the pass headlamp if you ever decide to add headlamp relays.

Re: splice near horn relay??

i would like to install the headlamp relays eventually but that's a project down the road. my oe battery junction block on the rad support is long gone. with my bat. in the trunk my air intake/cleaner maf sensor etc. takes up the spot of the original bat. location. is this stuff not that deep and i'm overthinkin' it?

Only if you let it overtake, will it become deep.

Re: splice near horn relay??

holy diodes batman-any electrical gurus confirm that this pic is the correct set up? my brown wire from the voltage regulator harness connects to the the yellow wire to alt. but as i peel off the electrical tape to make the connection i noticed this grey diode wired in parallel. anybody know bout' diodes? see pic

Re: splice near horn relay??

Diode may be an anti-feedback diode preventing engine to continue running once the ign is turned off, as if ign sw is still turned to IGN position.
If diode is not in the circuit, the alt is still turned 'on' and feeding electrical power to the rest of the elec system. Follow the brown wire in the schematic and you should find the brown wire goes back to the ign switch, thus to the rest of the elec system.

You are making a schematic of the wiring as you go along so later in life, you can refer to the drawing for troubleshooting purposes?
A picture of the back side of the alt, including the two-wire connector?

Re: splice near horn relay??

here's a pic of the back of alt. is it a cs130 or 12? any dif? the 2 wire plug on the back is: big red wire connects to the big pink wire that goes to the firewall bulkhead and the yellow wire (with the grey diode) connects to the brown wire from original voltage regulator harness. the seperate red wire mounted on the stud of the alt i'm gonna route to the horn relay. i got a decent understanding of how stuff works (enough to be dangerous!) but the electrical part was always kinda voodoo to me. props to Everett explaining the diode thing-guys like you make this site awesome
