I've only used cs130's (105a)on all my builds (BB,SB,G3), technically a 2 wire, you already have the "exciter wire", just connect the blue wire from the ballast resistor to the vr to the green stator wire from the alt to the vr , when you remove it (the vr). A
dd the required inline resistor (available with the connector),bypass the bulkhead with at least 8ga. cable to the battery. they are cheap and readily available, will accept both v and multi groove (serp) pulleys. the first BB I did I used the factory brackets, same with the first SB, then CVF came out with a bracket set and complete kits. If it's a bucks down thing and you're interested ....1992 suburban 1500 5.7 105a. and change the pulley to a gm v groove. here's a pic of the mock up, the triangle brackets offset is flattened out
