Horn Relays- 2 horn vs. 4 horn

[moving2]

Hi Guys- I'm getting ready to install a 4 Horn setup from late 80s Cadillacs into my truck (97 Landcruiser). Not knowing much about horn relays, I was planning to use my existing horn relay. Considering my stock setup consists of 2 horns, and I will be upgrading to 4 horns, do I need to get another relay for the other two horns, or can I just wire them all with my stock relay? If I do need 2 relays, do I need to get the Caddy relays, or can I just use two of my own stock relays? Thanks in advance for any help!

Hi Moving
The relays I'm used to using have an amp rating. I would say the easiest thing to do is use just one relay. Find out how much your horns are going to draw. You may have to buy a bigger relay. Having said that, there will be more juice flowing through the primary wires. Are they up to snuff? It would be funny seeing a Landcruiser burst into flames with its horns screaming. (OK, maybe funny for me)
