what details do you need?which one did you buy?i don't have any pictures that i can post(no scanner)but i looked back and the one i used before was a single outlet solenoid.it was plumbed into the rear line out of my master cylinder.a lot of guys i think plumb it differently, but it worked ok for me.I'm sure someone else will chime in with something else that will help and/or be better than what i did.what else do you need to know for this install?let me know.

well,i put mine into the line closest to the firewall.the rear one.i took the line loc to the part store and found a fitting that fit the in/out of the solenoid.i don't know the size.i just matched up the fittings that came out of the master and then matched the fitting size for the diameter line that i removed that goes to the portioning valve.you could flare the stock line and reuse it for the outlet side if need be.your going to need an adapter or two,the size is pretty small on those compared to the stock brake fittings it seems like a huge pain to try and do it with out any all.sorry i don't have any more info/pictures for ya that could help.

On cars with dual master cylinders & combination valves, line locks have to be installed after the combo valve. If you install it before the combo valve, it can lock all four wheels. At best it can trip the pressure switch & make the "brake" light stay on...
The NHRA will fail you at tech if the line lock is before the combo valve/distribution block, too...

.......sounds like you're not using the 'correct' adapters.
