P1 Input Connector:
5 Pin AMP Universal MATE-N-LOCK Connector UL94V-2 Nylon, mouser part # 571-6404661
P2 Driver Outnput Connector:
4 Pin AMP Universal MATE-N-LOCK Connector UL94V-2 Nylon, mouser part # 571-3504301"
P3 Tweeter Output Connector:

C1 24uF Capacitor:
Sonicap Gen-I 24uF Cap, Can be had here “www.soniccraft.com” (of course you can use any Cap you want but these boards were designed with Sonicap's in mind).
C2-A / C2-B 27uF Capacitor:
Sonicap Gen-I 27uF Cap, Can be had here “www.soniccraft.com” (of course you can use any Cap you want but these boards were designed with Sonicap's in mind), Also if you decide to use a 55uF Cap “Soniccraft doesn't make one” instead of 2 27uF (54uF total well with in %10) Caps you only need to place it in one of the C2 spots C2-A or C2-B just leave the other one blank.
C3 12uF Capacitor:
Sonicap Gen-I 12uF Cap, Can be had here “www.soniccraft.com” (of course you can use any Cap you want but these boards were designed with Sonicap's in mind).
C5 12uF Capacitor:
Sonicap Gen-I 12uF Cap, Can be had here “www.soniccraft.com” (of course you can use any Cap you want but these boards were designed with Sonicap's in mind).
BG 1.3 Ohm Resistor:
Is placed at holes B and G, A Mills MRA-12 1.2 Ohm resistor (well with in %10 of 1.3) is a good choice and can be had here “www.soniccraft.com” (of course you can use any resistor you want but these boards were designed with Mills in mind).
L1 1.25mH Inductor:
This comes from your original crossover board. It is in the same location and orientation on the new board as it is on the original board.
L2 1.00mH Inductor:
This comes from your original crossover board. It is in the same location and orientation on the new board as it is on the original board.
0.3mH Inductor:
This comes from your original crossover board. It is in the same location and orientation on the new board as it is on the original board. It connects to holes C and N
S1 Jumper:
Solder a jumper here (NOTE: The SDA SRS 3.1TL dosen't use a Polyswitch), You can use the legs you clipped off the Resistors or Caps after you have soldered them in.
J5 Jumper:
Solder a jumper here, You can use the legs you clipped off the Resistors or Caps after you have soldered them in.
EH Jumper:
Solder a jumper between holes E and H (Note: You should insulate this jumper, There is a possiblty that the lead from the 0.4mH inductor that go's to hole C could rub against this jumper), You can use the legs you clipped off the Resistors or Caps after you have soldered them in.
P and R Wires:
These wires connect to the big round 18mH Inductor. NOTE: You can optionly use a 3 Pin AMP Universal MATE-N-LOCK Connector UL94V-2 Nylon, mouser part # 571-3504291, Just don't use the center pin.
